Bulletin

The Sun produced seven C flares and one M flare during the past 24 hours. NOAA AR 1944 was responsible for most of the flaring activity. NOAA AR 1944 has grown in size and evolved to a beta-gamma region. NOAA AR 1936 shows some decay and is approaching the west limb. More M flares are possible (probability 50%), especially from NOAA ARs 1936 and 1944. There is a slight chance for an X flare (15%). We maintain the warning condition for proton events. Solar wind speed measured by ACE reached a maximum of 650 km/s, but has now declined to about 500 km/s. The magnitude of the interplanetary magnetic field declined from 8 to 4 nT, with a Bz- component varying between -6 and +5 nT. Estimated NOAA Kp and local K_Izmiran reached a maximum of 5 due to the influence of the coronal hole high speed stream. Current geomagnetic conditions are quiet to unsettled (Kp and K_Izmiran 2 to 3). Unsettled to minor storm conditions (local K 3 to 4) are possible due to the possible arrival of the CMEs of December 29 and December 31.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 100, sur la base de 07 stations.
