Bulletin

Flaring activity was at C class level since our last bulletin. A C4.4 flare with a peak on January 11 at 8:35 UTC was the strongest event and originated from Catania sunspot group 98 (NOAA AR 1944). More C flares are expected within the next 48 hours. Chances for M flares are estimated at 40% and for X flares at 10%. The proton event for the >10MeV protons is, strictly speaking, still going on, but the proton flux is expected to be below the event threshold (10 pfu) within the next few hours. The solar wind speed had values between 400 and 450 km/s. The magnitude of the interplanetary magnetic field reached a maximum value of 7 nT, with a Bz- component between -4 to +5 nT. Geomagnetic conditions were at quiet (K=0 to 2). Quiet to active levels (K=0 to 4) are expected within the next few hours due to the arrival of a coronal hole high speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 098, gebaseerd op 14 stations.
