SDO EVE Cruciform

Today, Jan 27, SDO is performing maneuvers designed to help the EVE team more fully understand its instrument. These spacecraft maneuvers, called cruciforms as they point the spacecraft in a cross-like pattern at multiple steps, happen twice a year. You may notice the Sun stepping across the AIA or EVE/SAM images, or missing altogether today. Don't worry, just another planned calibration activity to help SDO achieve the best possible data!

SDO research is the cover story of Science Magazine

An article on the heating of the solar corona is the cover story of the current issue of Science Magazine. The paper, written by Bart DePontieu et al., is an excellent example of research that has been made possible by SDO's high-resolution capabilities.

SDO Images are Available

The JSOC is repaired, the pipeline is running, and the images are again flowing to our near-realtime partners. Just in time for the region with the large prominence that erupted at the beginning of December to come across the disk.

Happy New Year, but better, Happy Perihelion at 1900 UT (2 pm ET) today!

JSOC is not processing data

The SDO JSOC has experienced a disk controller failure. The near-real-time images will not be produced until the controller can be replaced. Stay tuned for updates.

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."
