Bulletin

Flaring was eruptive featuring several C-class flares from NOAA active regions 1818, 1819 and 1825. Two CMEs were observed in the past 24 hours. The CME observed by LASCO/C2 on 19 August at 23h12 UT seems backsided and is not geo-effective. The CME observed on 20 August at 8h12 UT is associated to a large filament eruption. The CME travels with a speed of 600 km/s calculated based on STEREO data and goes mostly south of the ecliptic plane. There is a chance that Earth will be affected by the northern part of the CME structure, arriving late 23 August, possibly resulting in active to minor storm conditions. Current geomagnetic conditions are quiet to unsettled. Periods of enhanced geomagnetic activity are possible (unsettled to active) for the next 48 hours, in relation to the arrival of the equatorial coronal hole high speed stream and the CME of August 17.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 084, basierend auf 14 Stationen.
