Bulletin

The strongest flare of the last 24 hours took place in NOAA 2125. The C2 flare peaked at 14:10UT and was associated to a non-Earth directed CME. The 4 other C-class flares were all minor C1 events taking place in the trailing portion of growing active region NOAA 2126.The other 8 sunspot groups were quiet, including NOAA 2127 which has some mixed magnetic polarities. Further C-class flaring is expected, in particular from NOAA 2126 and 2127. After yesterday's sector boundary crossing, solar wind speed decreased from 450 to 350 km/s. Initially, Bz varied between +6 and -6 nT, but its amplitude gradually decreased to 2 near the end of the reporting period. Geomagnetic conditions evolved from unsettled to quiet. Quiet geomagnetic conditions are expected, with locally an unsettled period possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 100, basierend auf 15 Stationen.
