Bulletin

Solar activity has been low, no C-class flares in past 24 hours. The activity levels are expected to increase while a recurring active region rotates over the eastern limb. There was a partial halo CME seen at 02:15 UT by LASCO-C2 after a data gap, apparently originating in a filament eruption over the western limb. Part of the material is backsided and the bulk of the CME is directed towards the south, so most likely the Earth will not be affected. Solar wind speed is currently at 300 km/s with interplanetary magnetic field intensity at 6 nT. Geomagnetic conditions are quiet and expected to remain so.

Today's estimated international sunspot number (ISN): 054, based on 13 stations.
