Bulletin

The strongest flare of the past 24 hours is the C4.7 flare peaking at 05:10 UT today in the NOAA AR 2087 (Catania sunspot group 81). Although this group has the beta configuration of its photospheric magnetic field, emergence of new photospheric magnetic flux indicates that this active region may still produce more flares. NOAA AR 2089 (Catania number 82) has beta-gamma-delta configuration of its photospheric magnetic field, but it is currently producing only weak and confined C-class flares. We expect the flaring activity to continue on the C-level, with an M-class flare possible but not very likely. The Earth is currently inside a slow (around 360 km/s) solar wind flow with slightly elevated (around 6 nT) interplanetary magnetic field magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 067, based on 11 stations.
