Bulletin

NOAA ARs 2209 and 2216 (Catania numbers 9 and 14 respectively) have delta-spots in their trailing parts and continue to produce C-class flares. The strongest flare of the past 24 hours was the C8.1 flare peaking at 01:01 UT today in the NOAA AR 2209 (Catania number 9). We expect flaring activity on the C-level, possibly with an isolated M-class flare. A long filament in the northern hemisphere is now situated across the solar central meridian. Its eruption may lead to an Earth-directed CME. The Earth is currently inside a slow (around 370 km/s) solar wind flow with slightly elevated (7-8 nT) interplanetary magnetic field magnitude. Due to low solar wind speed, the geomagnetic conditions remained at the quiet to unsettled level (K < 4), with one interval of active conditions (K = 4) reported only by IZMIRAN yesterday evening. The geomagnetic conditions are expected to stay at the quiet to unsettled level (K < 4), possibly with isolated intervals of active conditions (K = 4).

Today's estimated international sunspot number (ISN): 060, based on 14 stations.
