MM#009 Default HESSI Target

Dear RHESSI Collaborators,

The target region (now numbered NOAA 2242) was the source of an isolated M1.6 event at 12/14/19:33 UT. 2242 also produced numerous C-class events. 2242 has a D-type/beta-gamma "self-contained" sunspot group. The leading sunspot has an unusual E-W magnetic inversion line and opposite polarity umbrae within a common penumbra but they are located too far apart to be classified as a true delta configuration. Emerging flux located in the trailing spots might be forming a small delta. C-class events expected with the chance of another M-class event in the next 24 hour period.

The position of NOAA 2242 on December 15 at 12:30 UT is: S20E31 (Solar X = -473", Solar Y = -321")
