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.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 077, sur la base de 04 stations.
