An active region on the Sun unleashed two blasts in quick succession (Jan. 19, 2012), which have sent particle clouds headed towards Earth. The images combine the wider field of view from SOHO's C2 coronagraph with the Sun itself as seen in extreme UV light by Solar Dynamics Observatory (SDO). The initial burst above the Sun is from the sar side of the Sun and not headed our way. The next two bursts, one quickly following the other, are from the bright active region seen near the 10 o'clock position. A series of coronal loops rise up above the active region after these events. The impact on the geomagnetic storm Earth may cause some bright auroras. The video covers about 24 hours of activity.

 

SOHO began its Weekly Pick some time after sending a weekly image or video clip to the American Museum of Natural History (Rose Center) in New York City. There, the SOHO Weekly Pick is displayed with some annotations on a large plasma display.

If your institution would also like to receive the same Weekly Pick from us for display (usually in Photoshop or QuickTime format), please send your inquiry to steele.hill@gsfc.nasa.gov.
