Bulletin

Solar activity was eruptive featuring 1 C-class flare (C2.6) originating from AR NOAA 11836. Both AR NOAA 11835 and NOAA 11836 have a possibility in producing M-class flares. A partial halo CME was detected by LASCO C2 on August 31st around 20:48 UT which could be assiociated with the C2.6 flare. This CME is mainly westward directed (possibly only a glancing blow) and due to the relative slow speed of 400 km/s will probably not have any influence on geomagnetic conditions. Current solar wind speed is around 550 km/s and the interplanetary magnetic field Bz component is around 0 nT. Geomagnetic conditions where quiet in the past 24 hours, but the CME of August 30th 2:48 UT might still arrive and potentially result in minor storm levels (K=5). The CME of of August 29th 06:00 UT is expected to arrive with a shock on September 2d in the evening resulting in active conditions (K=4).

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 049, basierend auf 07 Stationen.
