Bulletin

Solar activity has become less active in the last 24 hours with the decay of NOAA AR 1652. There were several C flares coming from both NOAA AR 1652 and 1654 with the strongest one a C3.4 flare from NOAA AR 1654 peaking at 15:46 UT. C flaring is still likely to occur especially from NOAA AR 1654 with a small chance for an M-flare. There was a filament eruption in the South-West region around 7:15 UT associated with a CME, but it is unlikely to become geo-effective. An increase of the electron levels (especially 0.8 MeV) has been detected since January 14th 06:30 UT and has reached a maximum level of almost 50000 pfu since January 14th 15:00 UT and this level has been maintained until now. Geomagnetic conditions have been quiet and are expected to remain so for the next 48 hours.

Today's estimated international sunspot number (ISN): 077, based on 04 stations.
