Bulletin

The strongest flare of the past 24 hours was the C6.1 flare peaking at 10:13 UT today in the NOAA AR 1960 (Catania number 18). Two weaker C-class flares originated from two active regions currently situated right behind the east limb: one in the northern hemisphere and one in the southern. We expect flaring activity to continue on the C-level, with an isolated M-class flare possible but unlikely. The Earth is currently inside a slow (around 360 km/s) solar wind flow with average (around 4 nT) interplanetary magnetic field magnitude. We expect quiet geomagnetic conditions.

Today's estimated international sunspot number (ISN): 074, based on 08 stations.
