Bulletin

NOAA AR 2010 produced today, March 20 an M1.7 flare with peak at 03:56UT. A type II outburst was detected. PROBA2 SWAP running difference images shows the coronal footprint of a CME which has only a faint appearance in COR2/STEREO B, not in LASCO/SOHO. NOAA AR 2014 rotated over the east limb and was the source of a C8.3 flare and a plasma eruption. We expect more activity from this region. We estimate a chance for more M-flares to be slightly above 50%. The solar wind speed is still below 400 km/s. The geomagnetic conditions are quiet. A small equatorial coronal hole is situated near the central meridian. It might become geoeffective in 3-4 days.

Today's estimated international sunspot number (ISN): 091, based on 16 stations.
