MAJOR FLARE: Earth-orbiting satellites detected a major X9-class solar flare this morning at 1035 UT (5:35 a.m. EST). The source: big, new sunspot 930*, which is emerging over the Sun's eastern limb. GOES-13 captured this X-ray image of the blast:
Because of the sunspot's location near the limb, the flare was not Earth-directed. Future eruptions could be, however, because the Sun's spin is turning the spot toward Earth. Sunspot 930 will be visible for the next two weeks as it glides across the solar disk.

SOLAR TSUNAMI: When sunspot 930 exploded on Dec. 6th, producing an X9-category flare, it also created a tsunami-like shock wave that rolled across the face of the sun, wiping out filaments and other structures in its path. A telescope in New Mexico operated by the National Solar Observatory recorded a must-see movie of the wave...

"These large scale blast waves occur infrequently, however, are very powerful," says Dr. K. S. Balasubramaniam of the National Solar Observatory. "They quickly propagate in a matter of minutes covering the whole sun and apparently sweeping away filamentary material." Researchers are unsure whether the filaments were blown off or were compressed so they were temporarily invisible.

| Okay, so what happens when the sunspot flares while pointed at earth? gives me some idea on what preparations to make for my family. |

What do Arizona and Alaska have in common? Northern Lights appeared over both states on Dec. 14th when a coronal mass ejection (CME) hit Earth, sparking a severe geomagnetic storm. The spectacular display is documented in a new photo gallery at http://spaceweather.com .
Another coronal mass ejection (CME) is on the way and due to arrive on Dec. 16th. This CME is not heading directly for Earth, and so it will deliver only a glancing blow. Nevertheless, NOAA forecasters estimate a 50% chance of severe geomagnetic storms. Sky watchers should remain alert for more auroras.

COMET MCNAUGHT: "When I stepped outside this morning, I stopped short on my doorstep. The morning sky was marvelous," says Andreas D. Skjervold of Boda, Norway. "Comet McNaught was shining almost as brightly as Venus: image."
"It was a morning to remember," agrees P-M Heden who took this picture from Vallentuna, Sweden:
"I saw the comet easily with my naked eyes," he adds. "I hope everybody goes outside to see it."
To see Comet McNaught, a clear view of the horizon is essential. In the morning, go outside and face east. The comet emerges just ahead of the rising sun. In the evening, face the other way--west. The comet pops out of the western twilight as soon as the sun sets. Binoculars reveal a pretty, gaseous tail.
Northern observers are favored. The long, dark mornings and evenings of Canada, Scandinavia and Alaska are ideal for viewing this comet so close to the Sun. But the comet has been sighted in other places, too, as far south as Kansas in the United States and Italy in Europe.

You can watch the comet near the sun live on the SOHO satellite starting Jan 11th, 2007
The SOHO live feed site is here...

LOTS of sun screen and get a camera because you might see the Auroras in Florida 
As long as the magnetosphere of the Earth holds out it would only disrupt communications and put on a pretty light show.

ROCKET EXPLOSION
February 19, 2007
Australian astronomer Ray Palmer was photographing the Southern Cross from his observatory in Western Australia on Feb. 19th when a flaming plume cut across the Milky Way. "I had no idea what it was," he says. "It was moving very slowly and I was able to track it for 35 minutes."
In mid-apparition the object exploded. Gordon Garradd of New South Wales photographed an expanding cloud filled with specks of debris. Tim Thorpe of South Australia saw it, too. "Quite a surreal scene," he says.
What was it? It was a mystery for almost 24 hours until satellite expert Daniel Deak matched the trajectory of the plume in Palmer's photo with the orbit of a derelict rocket booster--"a Briz-M, catalog number 28944."
In mid-apparition the object exploded. Gordon Garradd of New South Wales photographed an expanding cloud filled with specks of debris. Tim Thorpe of South Australia saw it, too. "Quite a surreal scene," he says.
What was it? It was a mystery for almost 24 hours until satellite expert Daniel Deak matched the trajectory of the plume in Palmer's photo with the orbit of a derelict rocket booster--"a Briz-M, catalog number 28944."
One year ago, the Briz-M sat atop a Russian Proton rocket that left Earth on Feb. 28, 2006, carrying an Arabsat-4A communications satellite. Shortly after launch, the rocket malfunctioned, leaving the satellite in the wrong orbit and the Briz-M looping around Earth partially-filled with fuel. On Feb. 19, 2007, for reasons unknown, the fuel tanks ruptured over Australia.
Jon P. Boers of the USAF Space Surveillance System confirms the ID and notes "later, on the other side of the world, our radar saw 500+ pieces in that orbit." Today the count is up to 1111 fragments. "[We're seeing] more fragments as the cloud expands," he explains.
Some of the fragments are visible in this movie made by Rob McNaught at the Siding Spring Observatory, NSW, Australia:
"Spica is at the right edge of the animation and the fragments are moving to the north and east," he says.
One thousand-plus fragments makes this "a major breakup event," says Mark Matney of NASA's Orbital Debris Office at the Johnson Space Center. "There is no immediate threat to the space station, but we're analyzing the orbits to assess any long-term hazard."
"Unlike recent high profile breakups, Briz-M is in an orbit that is difficult for most radars to see," adds Boers. "The generation of element sets on all the pieces will take weeks to accomplish."
