Bulletin

Solar activity was at very low levels. NOAA 2781 (Catania 50) was the source of a B7 flare peaking at 23:59UTC. NOAA 2782 (Catania 52) decayed further and lost most of its spots. Old active region NOAA 2778 is about 1 day behind the southeast imb. Solar activity is expected to be at very low levels, with a small chance on an isolated C-class flare. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels and is expected to remain so. The greater than 2 MeV electron flux was well below the 1000 pfu alert threshold and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain so.

Solar wind speed was on a generally declining trend, varying between 400 and 320 km/s (DSCOVR). Bz varied between -4 and +4 nT. The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector).

Geomagnetic activity was at quiet levels. Geomagnetic conditions are expected to be at quiet levels, with a small chance on an unsettled episode.

Today's estimated international sunspot number (ISN): 020, based on 16 stations.
