Global Eruption Rocks the Sun

Dec. 13, 2010: On August 1, 2010, an entire hemisphere of the sun erupted. Filaments of magnetism snapped and exploded, shock waves raced across the stellar surface, billion-ton clouds of hot gas billowed into space. Astronomers knew they had witnessed something big.

It was so big, it may have shattered old ideas about solar activity.

"The August 1st event really opened our eyes," says Karel Schrijver of Lockheed Martin's Solar and Astrophysics Lab in Palo Alto, CA. "We see that solar storms can be global events, playing out on scales we scarcely imagined before."

December 6th Filament caught by STEREO

The extraordinary Filament eruption caught by SDO on December 6, 2010 was also seen by the STEREO behind spacecraft.

The images and movies can be viewed here

New addition to the SDO data section

There is a new addition to the SDO data section of the website. We are now producing 48 hour subfield movies. These movies are similar to youtube in that they are streaming videos. The .flv files are updates every 30 minutes and there are five movies for every limb of the sun.

The subfield player can be accessed here

Guide Telescope Adjustments

Today (December 9) the AIA Science Team is adjusting the guide telescopes on AIA. One of these small telescopes is mounted above each science telescope, allowing the pointing to be precisely controlled. Every so often we need to tune the control tables. Today was one of those times. Small motions of the images will be seen in the data on the SDO website.

A 'snake' slithers across the sun

John Roach writes:NASA's Solar Dynamics Observatory has captured what appears to be a giant snake slithering along the sun's southeastern limb. The feature is actually a magnetic loop of dense gas suspended over the solar surface.


The snaky filament, which was first noticed last week by NASA's STEREO-B spacecraft stationed over the sun's eastern horizon, showed signs of instability and had the potential for an impressive eruption, according to SpaceWeather.com. You've got to see SpaceWeather's time-lapse animated image of the flare-up.
