Dear RHESSI Collaborators,

The current level of solar activity is low. Yesterday's target (NOAA 11897) was only responsible for C-class activity since the previous message. Continued flux emergence is evident, but no mixed polarity spots or strong polarity separation lines are visible. On the other hand, NOAA 11900 was responsible for C-class activity and two M-class flares (a M1.2 flare on 16-Nov-2013 at 04:53 UT and a M1.6 at 07:49 UT). There is evidence for continued flux emergence in the region and the large following positive spot has merged with flux to the North, to form a mixed polarity spot. Furthermore, adjacent NOAA 11898 (to the South) also shows flux emergence, and exhibits at least two small mixed polarity spots. The target region is designated as NOAA 11900, but if your FOV allows, it should include NOAA 11898 (~7 degrees to the South). Further C-class activity is possible with a chance for further M-class flares.

The position of NOAA 11900 on 16-Nov-2013 at 17:20 UT is:

S19W38, ( 572", -350" )
