Far side flare, July 19, 2012

This far side flare arised in the same active region as the flare which released the well known "Super storm" 4 days later. STEREO A spacecraft was in the position in which the flare was directly visible. Following images show the region on 04:14 UT, 06:14 UT, 08:14 UT, 10:14 UT, 12:14 UT. The color mapping of these STEREO images is not identical with PM-NAFE applied to SDO AIA data. The reason is that 211 A channel is not available and it is replaced by 195 A channel.
