Dear RHESSI Collaborators,
The level of solar activity remains low. NOAA region 12147 has produced several B-class flares since yesterday's C1.8 flare (on 18-Aug-2014 at 13:37 UT), but has decreased in magnetic complexity by being classified as an alpha/H-type sunspot group. NOAA 12139 has continued in its decay, decreasing in area, number of spots and losing its polarity mixing to be classified as a beta/C-type sunspot group. However, this region was the source of the largest event since yesterday's message (a C1.2 flare on 18-Aug-2014 at 16:47 UT). Further C-class activity is possible over the next 24 hours, with a very small chance for an isolated low M-class flare.
The position of NOAA 12139 on 19-Aug-2014 at 14:30 UT is:
N13W32, ( 491", 119" )
