Bülletään

Solar activity has been low, there is potential for moderate conditions in NOAA ARs 1861 and 1865. They have been both producing C class flares, together with 1870 and 1867. AR 1865 produced the strongest flare in the past 24h: a C8.9 with peak at 14:32 UT on October 16. There was a slow faint full halo CME, seen first at 15:48 UT (first seen in LASCO C2). It was related with a C1.8 flare from NOAA AR 1870. The bulk of the material was directed towards the west, with a speed of 300 km/s. An impact with the Earth is possible early on October 21, although geomagnetic conditions are not expected to be greatly affected by this weak event. The solar wind speed at the L1 point is 450 km/s with magnetic fields around 4 nT. Geomagnetic conditions have ranged from quiet to unsettled, quiet conditions are expected for next 48h.
