Bulletin

There are currently 9 sunspot groups on the solar disk, but all are quiet. No C-class flares were recorded, with the x-ray flux varying between the C1.0 and C3.2 level (21:10UT). No earth directed CMEs were observed. A filament eruption occurred near the Central Meridian (30 degrees north) around 06:00UT, but analysis of the geo-effectiveness of any related CME is pending the availability of coronagraphic imagery. The two big filaments in the western hemisphere remained quiet. C-class flaring is expected, with a chance on an isolated M-class flare. Solar wind speed was stable around 380 km/s. Bz varied between -6 and +5 nT. Quiet to unsettled geomagnetic conditions were observed and are expected to remain so, with an active episode possible.

Today's estimated international sunspot number (ISN): 099, based on 12 stations.
