Double Solar Flare - August 22, 2005
SOHO satellite image of the double CME on August 22, 2005.

Yesterday, Aug. 22, a pair of coronal mass ejections (CMEs) blasted off the Sun and headed toward Earth. Geomagnetic storms and auroras are possible today, Aug. 23 and tomorrow, Aug. 24 in Alaska and Canada and possibly beyond.

The active region, known as AR 798, is located in the lower right corner of the image. The CMEs were associated with relatively small solar flares. NOAA reports that another flare is possible in Region 798.
