Bulletin

Only minor C class flares in past 24 hours, with a C3.1 from Catania 45 (NOAA 2157, peak 00:27 UT) being the strongest one. More C-class flaring activity can be expected, with M-flares less likely. Geomagnetic conditions have been quiet and are expected to remain so, unless a CME from a filament eruption from close to disk center on September 12 arrives to the Earth in the next 24 hours (no obvious CME could be detected).

Today's estimated international sunspot number (ISN): 068, based on 17 stations.
