Bulletin

There are currently seven numbered sunspot groups on the solar disc. Solar activity is still low, with only one C-class flare reported during last 24 hours. The C3.9 flare (peaked at 03:15 UT, on September 18) originated from the NOAA AR 1846 which just turned from behind the east solar limb. The C-class flares are possible, in particular from the NOAA ARs 1846 and 1847. The solar wind speed slightly increased and it is now about 400 km/s. The interplanetary magnetic field magnitude is currently 5 nT. The occasional short intervals of negative Bz component of the interplanetary magnetic field resulted in K=3, as reported by local stations Dourbes and Izmiran. The geomagnetic conditions are quiet to unsettled and expected to remain so in the following 48 hours.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 044, basierend auf 11 Stationen.
