In months! I post this here because this date also is parallel to the biggest solar minimum in recent history! Still think global warming is man made?



STUCK ON MARS: NASA is about to begin transmitting commands to its Mars rover Spirit as part of an escape plan to free the venerable robot from a Martian sand trap. Officials say there is little hope of freeing Spirit, with a best case senario of "severe wheel slippage" and "barely detectable forward progress." On the bright side, Spirit is stuck in a very interesting spot. Science@NASA has the full story.

AROUND THE BEND: The "green sun" pictured below is an ultraviolet-wavelength photo taken just hours ago by NASA's STEREO-B spacecraft. What lies beneath the circled thicket of hot plasma and magnetic fields? It could be the most active sunspot of the year.
User Image
The circle marks the location of sunspot 1029. In late October, sunspot 1029 materialized on the Earth-facing side of the sun and quickly established itself as the biggest active region of 2009. It produced more than ten C-class solar flares, single-handedly quadrupling the number of such eruptions since the year began. For the past 11 days, however, sunspot 1029 has been out of sight transiting the farside of the sun.

The sunspot is still invisible from Earth, but STEREO-B can see it because the spacecraft is stationed over the sun's eastern horizon. The glaring knot of extreme ultraviolet activity hides the sunspot's underlying dark core from STEREO's UV telescopes, and this limits how much we know about it. Has sunspot 1029 broken apart and diminished during its long farside transit? Or is it still its old active self? Answers will be revealed in 3 days when solar rotation turns sunspot 1029 toward white-light cameras on Earth. Stay tuned.

Great Balls of FIRE!!! Quiet, CC...)

GREAT WESTERN FIREBALL: Yesterday, Nov. 18th, something exploded in the atmosphere above the western United States. Witnesses in Colorado, Utah, Wyoming and Idaho say the fireball "turned night into day" and issued shock waves that "shook the ground" when it exploded just after midnight Mountain Standard Time. The fireball was so bright it actually turned the night sky noontime blue, as shown in this image from KSL TV in Utah:

http://www.ksl.com/?nid=148&sid=8714738

Although the fireball appeared during the Leonid meteor shower, it was not a Leonid. Infrasound recordings of the blast suggest a small asteroid hitting Earth's atmosphere and exploding with an energy of 0.5 to 1 kiloton of TNT. Experts liken the event to the Park Forest fireball of 2003, which scattered dozens of meteorites across a suburb of Chicago. Meteorites are likely from this fireball as well. Stay tuned for developing information about the possible fall zone.

More


Approximately 6 hours after the fireball, people in Utah and Colorado got another surprise. As the sun rose over those states, a twisting electric-blue cloud appeared in the dawn sky:

User Image

"These curious clouds on the horizon caught my attention just before sunrise," says photographer Don Brown of Park City, Utah. "They were strangely bright relative to the rest of the sky."

The cloud strongly resembles artificial noctilucent clouds formed at high altitudes by rocket and shuttle launches. Yet there was no (officially reported) rocket launch at dawn on Nov. 18th. Could the cloud be associated with the fireball? The geographical coincidence is certainly striking. Debris from the fireball should have dissipated by sunrise, but the cloud remains unexplained and a connection to the fireball cannot yet be dismissed. Just noting here, These kinds of clouds are ALWAYS seen after fireball sightings. Spooky!

WATER ON THE MOON: Last month when NASA's LCROSS spacecraft hit the Moon and failed to produce a bright flash, many observers thought the experiment was a dud. Think again.
http://science.nasa.gov/headlines/y2009/13nov_lcrossresults.htm

NASA has announced that LCROSS discovered water at the bottom of crater Cabeus near the Moon's south pole.

The primary evidence is spectral. When LCROSS's Centaur rocket hit the ground, it produced a faint cloud of vapor. High above, the LCROSS mothership analyzed the cloud using its near-infrared spectrometer. Some of the bumps and wiggles in the spectrum perfectly match the infrared signature of H2O:
User Image

The red curve traces what the spectrum would have looked like if the debris cloud had been made of nothing but moondust and pure water vapor. Points with error bars are the actual data. Clearly, water is present, but that's not all. "Along with the water in Cabeus, there are hints of other intriguing substances," says Anthony Colaprete, the mission's principal investigator the NASA's Ames Research Center. "The possibility of contamination from the Centaur rocket [has been] ruled out," so any unidentified compounds are likely native to the Moon.

What are these mystery substances? Remember, LCROSS targeted a "cold trap" where materials have been freezing and accumulating for billions of years. It could be almost anything. Researchers are still studying the spectra for clues. "Full understanding of the LCROSS data may take some time," notes Colaprete. "The data are so rich."

December 14th, 2009, 2009 Synopsis:

SUNSPOT 1034 PROGRESSION:

User Image

The anticipated magnetic region on the farside of the sun about a week ago did indeed rotate into view, and are displaying a vacillant symbol of decline and growth. The Sunspot first emerged on December 10th, and is currently approaching the mid-longitudinal region on the solar disk. At first, it was a fairly small sunspot, and has had a few cycles of rapid growth and simmering. This sunspot, when emerged, adjourned the painstaking 16 day long spotless stretch of minimal solar activity - and packing a punch while doing so! Sunspot 1034 has possessed a minor- yet remarkable in relativity to the current inactivity trough, Lower C-Class Solar Flare threat(See Spoiler for information on Solar Flare Classes.) Here is what The Sunspot looked like when first appeared to its current state on the sun(In EIT 284 filtering):

User Image

Here is its emergence over the sun's eastern limb:

Here is its progression in Magnetic Polarity display(MDI Magnetogram):

User Image

Here is its current position on the MDI Continuum disk:

User Image

Below are some closer range images of said inferno in their regular EIT forms, and Longitudinal Gauss/km gradients:

User Image

User Image

User Image


Sunspot 1034's Solar Flare activity has remained in the A class of intensity, subtly surpassing the B class line, but this may or may not change into something more significant. For the most part, for far, though, the emissions have remained about the same:

User Image

It is a comparable threat, and perhaps may evolve into something dangerous and exciting. As you can see, there are other active regions besides sunspot 1034, such as the bright area to the left of it - perhaps these may bore through the sun as new sunspots. I'll keep you guys posted.

Spoiler(Solar Flare Classessmiley
[spoiler]
Scientists classify solar flares according to their x-ray brightness in the wavelength range 1 to 8 Angstroms. There are 3 categories: X-class flares are big; they are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. M-class flares are medium-sized; they can cause brief radio blackouts that affect Earth's polar regions. Minor radiation storms sometimes follow an M-class flare. Compared to X- and M-class events, C-class flares are small with few noticeable consequences here on Earth.

GEMINID METEOR SHOWER PEAK:

Yesterday, December 13th, and today, December 14th, are the Geminid meteor shower peaks. Earth is currently in the midst of a debris and remnant cloud of comet 3200 Phaethon. The constistency and frequency of these sigthings are astounding. Over recent years, the frequency of Geminid sighting streaks have inclined significantly. Here is the frequency count thus far, as viewed from a collection of 32 registered worldwide observers in respect to their night-time hours:

Thanks Vho!

SOLAR ACTIVITY: The sun is showing signs of life. There are no fewer than five active regions on the sun's surface, shown here in an extreme ultraviolet photo taken this morning by the Solar and Heliospheric Observatory (SOHO):

User Image

Each circle contains a sunspot or proto-sunspot belonging to new Solar Cycle 24. After two years of record-low sunspot numbers and many month-long stretches of utter quiet, this is a notable outbreak. Whether it heralds a genuine trend or merely marks a temporary, statistical uptick in activity remains to be seen. Stay tuned!

anyone getting warmer temperatures?

SOLAR ACTIVITY: Yesterday, Dec. 22nd at approximately 0455 UT, magnetic fields around sunspot 1036 erupted, producing a C7-class solar flare. NASA's STEREO-A spacecraft was almost directly above the sunspot at the time of the blast and recorded this extreme ultraviolet movie:

User Image

The shadowy wave racing away from the blast site is a "solar tsunami"--a swell of hot, magnetized plasma about 100,000 km high packing as much energy as a million megatons of TNT. The tsunami petered out before it went more than halfway around the sun, but another manifestation of the blast is still going. The eruption hurled a faint coronal mass ejection (CME) into space and the billion-ton cloud should cross Earth's orbit on or about Dec. 25th. A glancing blow to Earth's magnetic field could spark polar auroras for Christmas.

So in related news:

BIG INTERSTELLAR DISCOVERY: The solar system is passing through an interstellar cloud that physics says should not exist. In the Dec. 24th issue of Nature, a team of scientists reveal how NASA's Voyager spacecraft have solved the mystery. Get the full story from Science@NASA.

Quote:
December 23, 2009: The solar system is passing through an interstellar cloud that physics says should not exist. In the Dec. 24th issue of Nature, a team of scientists reveal how NASA's Voyager spacecraft have solved the mystery.


"Using data from Voyager, we have discovered a strong magnetic field just outside the solar system," explains lead author Merav Opher, a NASA Heliophysics Guest Investigator from George Mason University. "This magnetic field holds the interstellar cloud together and solves the long-standing puzzle of how it can exist at all."

Voyager flies through the outer bounds of the heliosphere en route to interstellar space. A strong magnetic field reported by Opher et al in the Dec. 24, 2009, issue of Nature is delineated in yellow. Image copyright 2009, The American Museum of Natural History. User Image

The discovery has implications for the future when the solar system will eventually bump into other, similar clouds in our arm of the Milky Way galaxy.

Astronomers call the cloud we're running into now the Local Interstellar Cloud or "Local Fluff" for short. It's about 30 light years wide and contains a wispy mixture of hydrogen and helium atoms at a temperature of 6000 C. The existential mystery of the Fluff has to do with its surroundings. About 10 million years ago, a cluster of supernovas exploded nearby, creating a giant bubble of million-degree gas. The Fluff is completely surrounded by this high-pressure supernova exhaust and should be crushed or dispersed by it.

"The observed temperature and density of the local cloud do not provide enough pressure to resist the 'crushing action' of the hot gas around it," says Opher.

So how does the Fluff survive? The Voyagers have found an answer.

User Image

"Voyager data show that the Fluff is much more strongly magnetized than anyone had previously suspected—between 4 and 5 microgauss*," says Opher. "This magnetic field can provide the extra pressure required to resist destruction."

NASA's two Voyager probes have been racing out of the solar system for more than 30 years. They are now beyond the orbit of Pluto and on the verge of entering interstellar space—but they are not there yet.

"The Voyagers are not actually inside the Local Fluff," says Opher. "But they are getting close and can sense what the cloud is like as they approach it."

The Fluff is held at bay just beyond the edge of the solar system by the sun's magnetic field, which is inflated by solar wind into a magnetic bubble more than 10 billion km wide. Called the "heliosphere," this bubble acts as a shield that helps protect the inner solar system from galactic cosmic rays and interstellar clouds. The two Voyagers are located in the outermost layer of the heliosphere, or "heliosheath," where the solar wind is slowed by the pressure of interstellar gas.

Voyager 1 entered the heliosheath in Dec. 2004; Voyager 2 followed almost 3 years later in Aug. 2007. These crossings were key to Opher et al's discovery.

The size of the heliosphere is determined by a balance of forces: Solar wind inflates the bubble from the inside while the Local Fluff compresses it from the outside. Voyager's crossings into the heliosheath revealed the approximate size of the heliosphere and, thus, how much pressure the Local Fluff exerts. A portion of that pressure is magnetic and corresponds to the ~5 microgauss Opher's team has reported in Nature.

The fact that the Fluff is strongly magnetized means that other clouds in the galactic neighborhood could be, too. Eventually, the solar system will run into some of them, and their strong magnetic fields could compress the heliosphere even more than it is compressed now. Additional compression could allow more cosmic rays to reach the inner solar system, possibly affecting terrestrial climate and the ability of astronauts to travel safely through space. On the other hand, astronauts wouldn't have to travel so far because interstellar space would be closer than ever. These events would play out on time scales of tens to hundreds of thousands of years, which is how long it takes for the solar system to move from one cloud to the next.

"There could be interesting times ahead!" says Opher.






Allow me to re-quote the quote:

SOLAR ACTIVITY: This morning, Dec. 29th, a slow-moving coronal mass ejection (CME) lumbered over the western limb of the sun. A coronagraph onboard the Solar and Heliospheric Observatory (SOHO) recorded the eruption:

The billion-ton cloud could have come from any of several active regions now on the back side of the sun--namely, former sunspots 1035, 1036 and/or 1038. Earth is not in the cloud's path (and neither is Venus, despite how it looks in the SOHO movie) so the event will not produce any Northern Lights.

This kamikaze comet is probably a member of the Kreutz sungrazer family.

Several of these fragments pass by the sun and disintegrate every day. Most are too small to see. Today's fragment is a big exception.

BLUE MOON ECLIPSE: Blue moons--rare. Blue moons on New Year's Eve--really rare. A lunar eclipse of a Blue Moon on New Year's Eve--well, that's just ridiculous.

Yet that's exactly what happened on Dec. 31st in Europe, Asia, Africa and parts of Alaska. The Blue moon on New Year's Eve passed through the outskirts of Earth's shadow, producing this 8% lunar eclipse:

"The eclipsed 'Blue moon' rose over the Alaska Range just before sunrise," says photographer Calvin Hall of Palmer, Alaska. "It was a beautiful sight."

Hole in the Moon Could Shelter Colonists
http://www.space.com/scienceastronomy/091231-moon-hole-lava-tube.html
Quote:
The moon may not be made of Swiss cheese, but it appears to have at least one deep hole, a vertical skylight that could serve as a protective lunar base for future astronauts.

"We discovered a vertical hole on the moon," an international team of scientists recently announced.

The gaping, dark pit on the near side of the moon is as big as a city block and deep as a modest skyscraper. It is thought to be a collapsed lava tube, created perhaps billions of years ago when the moon was warmer and volcanically active. The moon, overall, is more than 4 billion years old.

The discovery, detailed in the journal Geophysical Research Letters in October, was made using data from the moon-orbiting Japanese SELENE spacecraft. It was not widely reported at the time, and the journal announced it today. The work was led by Junichi Haruyama of the Japanese Space Agency JAXA.

Safe haven?

Recent discoveries of water and water ice on the moon hold promise that astronauts could journey back and stay for longer periods, perhaps even establish lunar colonies. But a remaining hurdle to setting up a permanent moon base is devising shelter to shield colonists from radiation and meteor strikes that befall the gray world, which has no protective atmosphere or magnetosphere.

"Because lava tubes are sheltered from the harsh environment on the moon's surface, such tubes could one day be useful for lunar bases," the scientists said in a statement.

Similar Mars caves have found and also envisioned as potential shelters, should humans desire to return to a sort of modernized cave man existence.

Deep and wide

The hole is nearly circular, about 213 feet (65 meters) across with a depth of 262 to 289 feet (80-88 meters). Here's how scientists think it was created:

Flowing lava long ago left a tunnel with a roof of somewhat fragile, cooled lava, which later collapsed. The hole is in the Marius Hills region, an area known to have been volcanic.

"Lava tubes, underground cave-like channels through which lava once flowed, are commonly found on Earth," the researchers point out. Scientists have long debated whether the moon might have such caves, but no firm evidence had been found until now.





January 2, 2010 - NASA and ESA Announce Joint
Jupiter and Saturn Mission Priorities.
The last week of December 2009, NASA and European Space Agency (ESA) officials
decided in Washington, D. C., meeting to first pursue a joint mission to study Jupiter and its
four largest moons followed by another mission to visit Saturn moons, Titan and Enceladus.
Left: Artist's illustration of Tandem mission to orbit Saturn's largest moon, Titan, and explore
its liquid (methane) surface. Right: Jupiter's four largest moons, from top to bottom:
Io, Europa - which has largest liquid water ocean in the solar system - Ganymede
and Callisto. Timelines for spacecraft launches are dependent upon
budgets in both NASA and ESA. Images credit: NASA/ESA.



SUNSPOT SURGE: 2009 is ending with a flurry of sunspots. Indeed, if sunspot 1039 holds together just one more day (prediction: it will), the month of December will accumulate a total of 22 spotted days and the final tally for the year will look like this:
User Image
The dark line is a linear least-squares fit to the data. If the trend continues exactly as shown (prediction: it won't), sunspots will become a non-stop daily occurance no later than February 2011. Blank suns would cease and solar minimum would be over.

If the past two years have taught us anything, however, it is that the sun can be tricky and unpredictable.



BLUE MOON ECLIPSE: On Dec. 31st, the Blue Moon will dip into Earth's shadow for a partial lunar eclipse. The event is visible from Europe, Africa and Asia: map. At maximum eclipse, around 19:24 Universal Time, approximately 8% of the Moon will be darkly shadowed.

What on Earth?! Russia may send spaceship to knock threatening asteroid off course

Read more: http://www.dailymail.co.uk/sciencetech/article-1239424/Russia-send-spaceship-knock-asteroid-Earth-threatening-path.html#ixzz0baC9uO2U


Quote:
t sounds like the script of a Hollywood blockbuster, but Russia is considering sending a spacecraft to knock an asteroid off its path and stop a collision with Earth.

The head of the country's space agency, Anatoly Perminov, said a mission was being discussed, and other agencies would be invited to join the project.

Nasa says there is no chance of the 270m (885ft) asteroid Apophis smashing into Earth in its first flyby in 2029, and only a 1-in-250,000 chance of a collision in 2036.

But Mr Perminov insists the asteroid is a potential menace. He was vague about the evidence of a possible hit but said he had heard from a scientists that the asteroid is getting closer.

'I don't remember exactly, but it seems to me it could hit the Earth by 2032,' he said.

'People's lives are at stake. We should pay several hundred million dollars and build a system that would allow us to prevent a collision, rather than sit and wait for it to happen and kill hundreds of thousands of people,' Perminov said.

Scientists have long theorised about asteroid deflection strategies.

Some have proposed sending a probe to circle around a dangerous asteroid to gradually change its trajectory. Others suggested sending a spacecraft to collide with the asteroid and alter its momentum, or using nuclear weapons to hit it.

Mr Perminov wouldn't disclose any details of the project, saying they still need to be worked out. But he said the mission wouldn't require any nuclear explosions.

Hollywood action films Deep Impact and Armageddon, have featured space missions scrambling to avoid catastrophic collisions. In both movies space crews use nuclear bombs in an attempt to prevent collisions.

'Calculations show that it's possible to create a special purpose spacecraft within the time we have, which would help avoid the collision without destroying it (the asteroid) and without detonating any nuclear charges,' Mr Perminov said.

BIG SUNSPOT: Sunspot 1040 is busy growing again. In only 24 hours, it has expanded from a barely visible "sun-speck" to a planet-sized active region with 15 dark cores and a tangled magnetic field. Steve Riegel sends this picture from his backyard observatory in Santa Maria, California:

"On Sunday, the clouds opened up for some fantastic viewing," says Riegel. "I photographed the active region using a Lunt 60 solar telescope."

Sunspot 1040 is a member of new Solar Cycle 24. Its appearance continues a recent trend of intensifying solar activity. NOAA forecasters estimate a 10% chance of M-class solar flares during the next 24 hours. Stay tuned.

SOLAR FLARE: Old sunspot 1039 still has some life left in it. On Jan. 17th, it unleashed a strong solar flare and triggered a solar tsunami. Click on the image to set the scene in motion.

User Image

The eruption, which took place on the far side of the sun, was invisible from Earth. Nevertheless, NASA's STEREO-B spacecraft had a great view. STEREO-B is stationed over the sun's eastern limb where it can see things that we cannot. The sun's rotation is turning sunspot 1039 back toward our planet and it should emerge over the limb within the next 48 hours. Meanwhile, STEREO-B will continue to monitor developments.

UPDATE: Sunspot 1039 produced another eruption on Jan. 18th around 2036 UT. STEREO-B recorded an ultraviolet flare (movie) and SOHO tracked a bright coronal mass ejection billowing over the sun's eastern limb

*Warning*
The sun is more active now than in 2 years!

CRACKLING SUNSPOT: Sunspot 1041 (a.k.a. "old sunspot 1039") is crackling with solar flares. Over the past few days, it has produced five M-class eruptions. Click on the image to play a movie of the latest, an M2-flare recorded by STEREO-B at 1756 GMT on Jan. 20th:
User Image
The ongoing sequence of flares signals a sharp upturn in solar activity. Before this week, the last time the sun produced even a single M-class solar flare was in March 2008--almost two years ago. M-class solar flares have a moderate effect on Earth. Mainly, they boost the ionization of Earth's upper atmosphere and disturb the propagation of terrestrial radio signals.

NORTHERN LIGHTS: As predicted, a solar wind stream hit Earth's magnetic field on Jan. 20th and sparked bright auroras around the Arctic Circle. "There were fast-moving streamers and stunning coronas," says Petter Hamnes of Mo i Rana, Norway. "It was one of the best displays I've seen in a long time." He took this picture using his Nikon D300:
User Image
The solar wind's impact caused a geomagnetic storm registering 5 on the 0-to-9 K-index scale of magnetic disturbances. It was the first geomagnetic storm of the year--but probably not the last. With active sunspot 1041 turning toward Earth, there could be more in the offing. High-latitude sky watchers should remain alert for auroras.


IONOSPHERIC DISTURBANCE: An M2-class solar flare on Jan. 19th bathed Earth's upper atmosphere in X-rays and caused a wave of ionization to sweep over Europe. This improved the propagation of low-frequency radio signals, which use the ionosphere as a reflector to skip over the horizon. A SID monitor operated by Rudolf Slosiar in Bojnice, Slovakia, recorded a surge in signal strength:
User Image
"SID" stands for Sudden Ionospheric Disturbance, and a "SID monitor" is a radio receiver that monitors ~20 kHz signals from distant transmitters. "My system clearly detected the effects of the solar flare," says Slosiar. "The decay of the signal shows that it took about 72 minutes for the ionosphere to recombine [and relax to its pre-flare state]."

January 20, 2010 - What Is Dark Disk Material
Moving in Front of Epsilon Aurigae?
“We have increasing evidence that a dark disk of material
has moved in front of our view of Epsilon Aurigae. But the exact
shape and makeup of the disk has been unknown, but it will be better
defined soon.” - Robert Stencel, Scientific Advisor, Citizen Sky

User Image
Six months ago in August 2009, professional and amateur
astronomers reported that the bright star Epsilon Aurigae had begun
to lose brightness for the first time in 27 years. The star is a mysterious, bright,
eclipsing, binary variable that has puzzled astronomers for 175 years. “Under normal
circumstances, the star is bright enough to be seen from even the brightest of cities with
only the naked eye,” reported Astronomy. The National Science Foundation has
funded a 3-year Citizen Sky program to involve the public in monitoring this
and other astronomical puzzles. Illustration by Nico Camargo, CitizenSky.org.

red tendrils of deeper, darker dust. The yellow arrow points at a puff of sand caught in motion

RADIO-ACTIVE SUNSPOT: Behemoth sunspot 1045 is crackling with M-class solar flares--and that's not all. "There have been many loud shortwave radio bursts over the past two days," reports amateur radio astronomer Thomas Ashcraft of New Mexico. "Some of the bursts have completely saturated my receivers." Just listen to the sounds coming from the loudspeakers in his observatory.

The roaring sounds you just heard were mainly Type III radio bursts, caused by beams of electrons streaming through the sun's outer atmosphere. Sunspot 1045 appears poised to explosively accelerate more electrons in the days ahead as the flare-show continues. Ham radio operators, point your Yagis toward the sun!


NORTHERN LIGHTS: "As the solar wind swept over our planet tonight (Feb. 7th), the silent winter landscape with its heavy snow-clad trees made me feel that our place in the solar system must be among the most beautiful," says Fredrik Broms of Kvaløya, Norway. He used a Nikon D3 to record the otherworldly scene:

OLD TEACHINGS, BEWARE: The Solar Dynamics Observatory (SDO) is set to launch from the Kennedy Space Center on Feb. 10th. Researchers expect SDO to rewrite the textbooks on solar physics using a battery of advanced cameras, telescopes, and magnetic sensors--some of which can even peer beneath the sun's stormy surface. This is such a big event, the staff of spaceweather.com has traveled 3000 miles to witness the launch. Stay tuned for first-hand reports.
