Dear RHESSI Collaborators,
The current level of solar activity is low. NOAA 11899 was responsible for the largest event since the previous message; a M1.0 flare on 15-Nov-2013 at 02:29 UT. However, its magnetic configuration is simple and its structure remains stable. NOAA 11893 shows dynamics within its spot configuration; its north- most negative spot appears to be merging with the large following positive spot. Nearby NOAA 11900 is also showing continued flux emergence and a mixed polarity intermediate spot, but neither region exhibits significant activity. On the other hand, yesterday's target NOAA 11897 was responsible for continued C-class activity (the largest event being a C7.5 flare on 15-Nov-2013 on 11:35 UT) and showed further flux emergence in its NW portion. The region also exhibits a mixed polarity spot in its intermediate portion. Further C-class activity is expected with a chance for an isolated M-class flare.
The position of NOAA 11897 on 15-Nov-2013 at 18:50 UT is: S21E16, ( -247", -391" )
