Four low-level C-class flares were recorded. The strongest was a C1.9 peaking at 22:15UT and produced by NOAA 2172 from behind the west limb. The x-ray background flux has decreased below the C1-level. There are currently 8 sunspot groups visible on the solar disk. Most of them are fairly simple, and contain a filament or are close to one. Further C-class flaring is expected. A 20-degrees long, thin, but dynamical s-shaped filament has rounded the southeast limb. This area seems to have been responsible for a filament eruption on 03 October between 03:00 and 04:30UT. The associated CME was not directed to Earth. Solar wind speed increased from about 330 to 370 km/s. Bz was initially fluctuating around 0 nT untill about 05:00UT, when it gradually increased to the current +10 nT. Geomagnetic conditions were quiet to unsettled, and are expected to remain so, with locally an active episode possible.
Today's estimated international sunspot number (ISN): 079, based on 12 stations.
