Bulletin

Flaring activity is mostly originating from the North-East quadrant of the solar disc up to an M3.4 flare from NOAA AR 12149 near the NE limb on Aug 21 13:31. Continued M-flare activity is expected from this region, while also NOAA AR 2148 is expected to produce C-flares. Quiet geomagnetic conditions are expected in the coming 3 days: there are no high speed wind streams expected from coronal holes, nor are there any new CMEs on the way to the Earth.

Today's estimated international sunspot number (ISN): 092, based on 15 stations.
