Bulletin

AR NOAA 1652 and NOAA 1654 remain the most eruptive regions featuring several C flares with the highest value a C6.5 flare originating from NOAA 1652 peaking at 01:22 UT. A very faint and slow (260km/s) CME was observed in LASCO C2 at around 13:00 UT and confirmed with STEREO A and B. It is not likely that this CME will become geo-effective. Geomagnetic conditions have been quiet to active in the last 24 hours, we expect geomagnetic conditions to be mostly quiet during the next 48 hours.

Today's estimated international sunspot number (ISN): 081, based on 09 stations.
