Dear RHESSI Collaborators,

Solar flare activity continues at moderate levels. Three low M-class flares (M1.1 at 08/21/19:10 UT, M1.2 at 08/22/06:39 UT, and M2.2 at 08/22/13:17 UT) were produced by the target region NOAA 12403 in the previous 24 hours. 12403 was also the source of several high level C-class events. 12403 continues to increase in sunspot area and number of spots, and remains classified as a beta-gamma/D-type sunspot group. It is continuing to mix polarities in its intermediate portion. Seems that the magnetic field in its leading portion becomes stronger. C-class flares are expected, with a potential of (high) M-class activity.

The position of NOAA 12403 on August 22 at 14:35 UT is:

S14E14 (Solar X = -223", Solar Y = -336")
