Six C-class flares were measured during the past 24 hours. The strongest event was a C5.9 flare, peaking at 15:10 UT on December 10, originating from a filament region slightly west of NOAA 2230 (Catania 30). The associated CME is believed to be too narrow and directed to the South. Two other C-class flares erupted from new active region 2234 (no Catania number yet) which developed to a beta region. No geo-effective CME was observed in coronagraphic imagery. Flaring activity at the C-level is expected. A coronal hole with central location at N25E0 is passing the central meridian and is expected to cause the arrival of a high speed stream on December 14. Solar wind speed is gradually decreasing from 500 to about 400 km/s and the magnitude of the interplanetary magnetic field is relatively stable around 5 nT. The geomagnetic conditions were mostly quiet, with a time slot of active conditions (K=4 at Dourbes, 6-9 UT December 11). The NOAA estimated Kp remained below K=4 for the whole period. Quiet to unsettled conditions (K<4) are expected for the next 48 hours.
Today's estimated international sunspot number (ISN): 080, based on 07 stations.
