NASA released a new image of a solar flare from active region 1429.
On March 13, 2012, the sun erupted with an M7.9-class flare that peaked at 1:41 p.m. EDT (10:41 a.m. PDT). This flare was from the same active region, No. 1429, that has been producing flares and coronal mass ejections all week. That region has been moving across the face of the sun since March 2, and will soon rotate out of Earth view.
This is the sunspot region AR 1429 that has generated several major solar storms recently. The video covers nine days (Mar. 4 – 12, 2011). Notice how the spot continually changes as its magnetic fields realign themselves. The images are white light images called intensitygrams captured by NASA’s Solar Dynamics Observatory (SDO).
