Bulletin

Solar activity slightly increased during the period. NOAA 2699 active region, in spite of decaying magnetic configuration, produced multiple B-class flares and one C4.6 flare peaking at 13:21 UT yesterday. Proton flux levels are at background values and are expected to remain so. No Earth-directed CMEs were observed. C-class flares (and with a tiny chance M-class flares) are still expected. Solar wind speed is currently at 315 km/s with interplanetary magnetic field magnitude of 2.5 nT. Geomagnetic conditions have been very quiet. The fast speed solar wind coming from the transient low latitude negative polarity coronal hole will affect the Earth environment in 4-5 days from now. Mostly quiet geomagnetic conditions are expected in the next 3 days. Isolated episodes of unsettled conditions are not excluded due to occasional passages of transient features.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 030, basierend auf 12 Stationen.
