Bulletin

Nine active regions were reported by NOAA today, all with alpha or beta configuration of the photospheric magnetic field. The strongest flare of the past 24 hours was the C1.5 flare peaking at 23:44 UT yesterday in a region connecting NOAA ARs 1959 and 1960. We expect flaring activity to continue on the low C-level. The Earth is inside a slow (around 350 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): 072, based on 09 stations.
