Bulletin

Only one C-class flare was reported during the past 24 hours: a C1.3 flare peaking at 19:05 UT yesterday in the Catania sunspot group 15 (NOAA AR 1955). We expect flaring activity on the low C-level, in particular in Catania sunspot groups 14 and 17 (NOAA ARs 1957 and 1959 respectively) that keep the beta-gamma configuration of the photospheric magnetic field. The Earth is currently inside a solar wind flow with an intermediate speed (around 450 km/s). The interplanetary magnetic field magnitude is average (around 5 nT), so we expect quiet geomagnetic conditions.

Today's estimated international sunspot number (ISN): 112, based on 06 stations.
