MM#009 Default HESSI Target
Dear RHESSI Collaborators,
Target region NOAA 1719, N11W22, has decayed significantly losing its magnetic delta configuration. It was the source of only minor C-class events in the past 24 hours. NOAA 1718 produced an isolated M3.3 event at 04/12/20:38 UT. 1718 has decayed slightly since the M-class event but remains a D-type/beta-gamma region with the brightest plage on the visible disk. The target will switch from 1719 to 1718 today. There is a chance of another M-class event in the next few days.
The position of NOAA 1718 on April 13 at 13:00 UT is: N21W54 (Solar X = 723", Solar Y = 394")
