Bulletin

No C-class flares were reported in the past 24 hours. Catania sunspot groups 14 and 17 (NOAA ARs 1957 and 1959) keep the beta-gamma configuration of the photospheric magnetic field, so we expect flaring activity on the low C-level. A long filament in the southern solar hemisphere passed the central meridian. If it erupts, the associated CME is very likely to arrive at the Earth. The Earth is currently inside a slow (around 370 km/s) solar wind flow with average (4-5 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions.

Today's estimated international sunspot number (ISN): 089, based on 12 stations.
