Bulletin

The strongest flare of the past 24 hours was the M5.7 flare peaking at 17:48 UT yesterday in the NOAA AR 2209. It was not associated with a CME. The NOAA AR 2209 maintains the beta-gamma-delta configuration of its photospheric magnetic field, so we expect flaring activity on the M-level in this region, with an X-class flare possible but unlikely. The Earth is currently inside a slow (around 450 km/s) solar wind flow with average (around 5 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 072, based on 11 stations.
