Dear RHESSI Collaborators,
Solar activity is at a low level. NOAA regions 12146 and 12147 recently rotated over the East limb and both produced C1.8 flares in the past 24 hours (from 12146 on 17-Aug-2014 at 19:41 UT; from 12147 on 18-Aug-2014 at 13:37 UT). NOAA 12139 has shown signs of decay by decreasing in area, number of spots and now being classified as a beta-gamma/C-type sunspot group. This region has not produced any noteworthy activity in the past 24 hours, but has maintained some small opposite polarity spots in close proximity to the primary leading spots. More C-class activity is possible over the next 24 hours, with a small chance for an isolated low M-class flare.
The position of NOAA 12139 on 18-Aug-2014 at 16:00 UT is:
N14W23, ( 358", 128" )
