Bülletään

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.
