SOLAR ACTIVITY: An explosion on the sun yesterday produced a burst of 18-22 MHz radio waves so intense "it sounded like a freight train rolling through," says astronomer Thomas Ashcraft. He recorded the sounds using his shortwave radio telescope in New Mexico.

The source of the blast was an active sunspot hiding just behind the sun's eastern limb. For days it has been erupting and throwing clouds of magnetized gas high above the sun's surface where we can see them. Soon, we'll see the sunspot itself. The sun's rotation is turning the spot toward Earth and it could emerge later today. Stay tuned.

AURORA WATCH: A solar wind stream is expected to hit Earth later today, possibly sparking a mild geomagnetic storm. Sky watchers in Alaska, Canada and Scandinavia, be alert for auroras.

SUDDEN QUIET: Sunspot 923 has emerged from behind the sun's limb into full view. As expected, it's a big one:
Suddenly, however, sunspot 923 has gone quiet. The explosions that heralded the sunspot's approach earlier this week have ceased--temporarily? Stay tuned.

Hmm... the other day at work, some guy had a special solar telescope set up to show mercury crossing in front of the sun. I had trouble seeing mercury, but I did see that massive sun spot that is shown here. I didn't hear it make any noise, though. wink grin wink grin wink grin

I guess a lot of people saw it by accedent waiting to see the planet! So a lot of people got pretty good pix of it.

the sound it made in space sounds like this,

Apparently massave solar flares and radiation storms that could knock out cell phones and cause some black outs and very pretty aruras at the north pole. From what I've read, no one had ever seen that ripple effect on the sun before. Its also strange that a month to the day, it happend again at the same hole in the sun. You can check the dates when I started the thread it was november 8 or 9th and in december, yet again it blew up again. For now its quiet. It did knock out NOAAs satilite thats looking at the sun though. Donno when it will be back up

Here is what the sun looks like now that the hole is stable

this still gives me the willys and I think I'll stay out of the sun for the next few days. shocked

you know it doesn't really concern you "as much" until to accually see the comparison of earth on a scale model next to the flare shocked

I don't mean to worry anyone but I just heard about it doing it again.

*the little dot things that go flying is most probably radation*

They say things are going to get alot worse before they get better too... Already they are warning of sever radiation storms that will pass through the earth, Nasa has lost contact with its "ACE" satilite and do not know when it will be working again, NOAAs sat came back and grabed a few shots before going blank again.

If you would like to see from the site I am seeing go here:

here is a graph to show the magnitudes of diffrent solar flares. These are almost off the chart.

ok so that show of the sun (the green one) DID stir up quite a bit of trouble. I mean the story actually made it to a major news outlet. CNN reported on a massave solar storm heading this way. It prompted the space station to put up its radiation shield. Read more here.

http://www.space.com/scienceastronomy/061213_solar_storm.html

Quote:
Editor's Note: This forecast replaces the predictive aspects of this earlier story on the solar flare.

Space weather forecasters revised their predictions for storminess after a major flare erupted on the Sun overnight threatening damage to communication systems and power grids while offering up the wonder of Northern Lights.

"We're looking for very strong, severe geomagnetic storming" to begin probably around mid-day Thursday, Joe Kunches, Lead Forecaster at the NOAA Space Environment Center, told SPACE.com this afternoon.

The storm is expected to generate aurora or Northern Lights, as far south as the northern United States Thursday night. Astronauts aboard the International Space Station are not expected to be put at additional risk, Kunches said.

Radio communications, satellites and power grids could face potential interruptions or damage, however.

Solar flares send radiation to Earth within minutes. Some are also accompanied by coronal mass ejections (CME), clouds of charged particles that arrive in a day or two. This flare unleashed a strong CME that's aimed squarely at Earth.

"It's got all the right stuff," Kunches said.

However, one crucial component to the storm is unknown: its magnetic orientation. If it lines up a certain way with Earth's magnetic field, then the storm essentially pours into our upper atmosphere. If the alignment is otherwise, the storm can pass by the planet with fewer consequences.

Kunches and his team are advising satellite operators and power grid managers to keep an eye on their systems. In the past, CMEs have knocked out satellites and tripped terrestrial power grids. Engineers have learned to limit switching at electricity transfer stations, and satellite operators sometimes reduce operations or make back-up plans in case a craft is damaged.

Another aspect of a CME involves protons that get pushed along by the shock wave. Sometimes these protons break through Earth's protective magnetic field and flood the outer reaches of the atmosphere—where the space station orbits—with radiation. The science of it all is a gray area, Kunches said. But the best guess now is that there will only be a slight increase in proton activity. That's good news for the astronauts.

"When the shock goes by, we don't expect significant radiation issues," he said.

The astronauts were ordered to a protective area of the space station as a precaution last night.

Now that sunspot number 930 has flared so significantly—after several days of being quiet—the forecast calls for a "reasonble chance" of more major flares in coming days, Kunches said.
