Rapid Fire Flares
June 19, 2012
Over 20 flares blasted off in less than one day from a single, large active region just rotating into view of the SDO spacecraft (Apr. 11-12, 2011). That is a very active region. Because flares are too bright for SDO's imager, they produce staggered diffractions of light as artifacts, a telltale sign of flaring. We'll be sure to keep a sharp eye on this region as it rotates more towards facing Earth by about April 17th.
