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. However, the strongest flare of the past 24 hours was the C3.5 flare peaking at 10:53 UT today in the still unnumbered sunspot group that appeared from behind the east solar limb yesterday evening. We expect flaring activity on the C-level, possibly with an isolated M-class flare. A long filament in the northern hemisphere has finished crossing the solar central meridian, but its eruption may still lead to an Earth-directed CME. The Earth is currently inside a slow (around 400 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 mostly at the quiet to unsettled level (K < 4), only with one interval of active conditions (K = 4) reported by IZMIRAN and NOAA yesterday evening. The geomagnetic conditions are expected to stay at the quiet to unsettled levels (K < 4), with isolated intervals of active conditions (K = 4).

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 062, basierend auf 14 Stationen.
