X-ray background radiation is in the B-level. No C-flares occurred. Catania sunspot group 83/NOAA AR 1850 has the potential of producing a C-flare. It is located between 30° and 45° longitude. A large filament (longitudinal, between 5° and 30°) passed the central meridian. Up to now, it seems to be stable. Two coronal holes (CH) are visible on the solar disk: a small northern CH (between 35° and 50° latitude, 20° wide) crossed the central meridian on September 27 and a small equatorial CH (between 5°S and 5°N, 10° wide) that crosses the central meridian today. Unsettled geomagnetic conditions are possible from October 1-2. The geomagnetic conditions are quiet at the moment.
Today's estimated international sunspot number (ISN): 036, based on 15 stations.
