Bülletään

NOAA AR 1818 produced a complex eruptive event on August 17, resulting in two M flares within one hour: a M3.3 peaking at 1824 UT and a M1.4 peaking at 1933 UT. This complex event was associated with a fast CME (~1000 km/s as seen from COR2 A). The bulk of the CME appears to go essentially westwards, with respect to the Earth, but we might cross the eastern flank of this CME on the second half of August 20. The 10 MeV proton flux rose slightly but didn't reach the event threshold. Flaring activity is expected to remain at eruptive levels for the next 48 hours, with C class flares likely from NOAA ARs 1818 and 1824, and a slight risk of an isolated M class flare from AR 1818. We expect essentially quiet geomagnetic conditions for the next 48 hours. There is a small chance of periods of enhanced activity (unsettled to active) on the second half of August 20, due to the CME of August 17.
