Solar activity has been low over the past 24 hours, the strongest reported flare was the C3.9 flare on December 10 (peaking at 07:50 UT). The flare originated from the newly numbered NOAA AR 2468 currently situated at the East solar limb. The SDO/AIA observations indicate possibly associated CME, more will be reported as soon as coronagraph data become available. However, since this was limb event the associated CME will not arrive at the Earth. No Earth directed CMEs were observed in the last 24 hours. The Earth is currently inside the fast solar wind (about 600 km/s) from the equatorial coronal hole which reached the central meridian late on December 06. The in situ data show arrival of the compression region in front of the fast flow starting from about 22:00 UT on December 09. The interplanetary magnetic field magnitude is currently about 7 nT. The fast solar wind and the negative intervals of the Bz component of the interplanetary magnetic field induced disturbed geomagnetic conditions this morning (the local station at Dourbes reported value of K=4, and NOAA reported one interval of Kp=5). We expect active to minor storm geomagnetic conditions in the coming hours.
Today's estimated international sunspot number (ISN): 077, based on 11 stations.
