Bulletin

One M class flare was recorded in the past 24 h: M1.9 peaking at 17:43 UT on July 25 from NOAA AR 2567. As this AR rotated over the west limb, the visible Sun became spotless and flaring activity greatly reduced. C-class flares can still be expected from this AR in the coming hours. Geomagnetic conditions were mostly active during past 24 h due to (most likely) a small ICME that reached ACE around 15:00 UT on July 24 (corresponding to a CME that erupted on July 20). Solar wind speed is currently at 450 km/s with interplanetary magnetic field magnitude of 5 nT. Active conditions are possible within 48h in response to the arrival of the high speed stream from a northern coronal hole, as well as of the low- probability glancing blow from the 23 July CME.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 24 Stationen.
