Bulletin

Solar activity is still low with only three C-class flares reported during last 24 hours. Majority of the flares originated from the NOAA AR 1800 which has at the moment beta configuration of the photosperic magnetic field. The strongest flare was C3.1 flare which peaked at 08:44 UT on July 21. The flare was associated with the coronal dimming and therefore probably also with the CME. However, this cannot be confirmed due to the data gap in STEREO and SOHO/LASCO observations. We expect C-class flares and also possibly M-class flares. The solar wind speed is currently 400 km/s, and the interplanetary magnetic field magnitude is about 3 nT. We expect quiet to unsettled geomagnetic conditions.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 034, basierend auf 13 Stationen.
