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.
