公告

Solar activity was at active levels during the past 24 hours. The strongest event, an M9.9 flare, occurred in NOAA AR 1936 (no Catania numbering yet) and peaked on January 1 at 18:52 UT. The event was associated with a slow CME (estimated projected speed 400 km/s) with first observation in LASCO/C2 at 20:00 UT. This CME might reach Earth on January 5 around 22h UT. New region NOAA AR 1944, located at S05E76, also produced an M1.7 and three C flares. A prominence eruption occurred on January 1 from around 13:00 UT located in the southeast quadrant and seems associated with a CME. This CME mainly is mainly southward directed and is not expected to reach the Earth. More M flares are likely to occur, especially from NOAA ARs 1936 and 1944. There is a moderate chance for an X flare. We maintain the warning condition for proton events. Solar wind data measured by ACE indicate the arrival of a coronal hole fast speed stream. Solar wind speed is about 600 km/s. The magnitude of the interplanetary magnetic field reached a maximum of 17 nT, with a Bz- component varying between -13 and +8 nT. Current geomagnetic conditions are unsettled to active (Kp 3 to 4). Unsettled to minor storm conditions (Kp 3 to 5) are expected due to the possible arrival of the CMEs of December 29 and December 31.
