Bulletin

Catania 92 (NOAA AR 2096) produced the only C-class flare of past 24 hours, a C2.2 flare that peaked at 09:18 UT. More C-class flaring activity can be expected. The solar wind speed is at 350 km/s with interplanetary magnetic field magnitude of 5 nT. Geomagnetic conditions are quiet. The fast solar wind from an equatorial coronal hole is expected to reach the Earth within 48 hours, probably rising conditions to active levels.

Today's estimated international sunspot number (ISN): 048, based on 21 stations.
