公告

Five C flares and three M flares were measured by GOES during the past 24 hours. The strongest flare was an M1.3 flare with a peak time on January 4 at 10:25 UTC. NOAA AR 1944 was responsible for most of the flaring activity. NOAA AR 1944 has shown some growth in size and number of sunspots. NOAA AR 1937 has also grown and produced one C4.0 flare peaking on January 3 at 18:35 UTC. The chances for C flares are high (90%). Also more M flares are possible (probability 50%), especially from NOAA AR 1944. There is a slight chance for an X flare (15%). We maintain the warning condition for proton events. No Earth-directed CMEs were observed. Solar wind speed measured by ACE varied from 450 to 550 km/s. The magnitude of the interplanetary magnetic field is stable around 4 to 6 nT, with a fluctuating Bz- component varying between -6 and +5 nT. No signatures of any ICME arrival has been detected yet. Current geomagnetic conditions are quiet to unsettled (estimated NOAA Kp and K_Izmiran 1 to 3). Mainly quiet to unsettled conditions are expected to continue.

今日估計的國際太陽黑子數（ISN）：101，基於05個觀測站。
