01.22.12: SDO's View of M8.7 Solar Flare



Solar Dynamics Observatory captured the flare, shown here in teal as that is the color typically used to show light in the 131 Angstrom wavelength, a wavelength in which it is easy to view solar flares. The flare began at 10:38 PM ET on Jan. 22, peaked at 10:59 PM and ended at 11:34 PM.

01.22.12 - Closeup of M8.7 Solar Flare



This closeup of the January 22, 2012, M8.7 class solar flare was taken by the Solar Dynamics Observatory (SDO) in 304 angstrom. An earth-directed coronal mass ejection (CME) accompanied the flare.











01.22.12: SOHO's View of Earth-directed CME



The Solar Heliospheric Observatory captured the coronal mass ejection (CME) in this video (which shows the sun's activity from January 19 to January 23). The CME is associate with an M8.7 class solar flare from AR1402. The end of the movie shows the interference caused by the onslaught of fast, energetic solar particles emitted from the sun.

Jan. 19, 2012 - M3.2 Solar Flare and CME



Our increasing active sun let loose a long duration M3.2 class flare and coronal mass ejection (CME) between 15:15 and 16:30 UT today. The CME is Earth directed with impact predicted for Jan. 21, 2012.

This video taken by the Solar Dynamics Observatory, shows a close-up of sunspot 1401 region as the flare erupts. The CME cloud lifting off is visible just past midway in the video. Across the top is a graph of corresponding X-ray measurements taken by the GOES 15 satellite.
