Bulletin

Several minor C-class flares were observed by GOES, mainly originating from NOAA AR 1820 and 1828. A CME observed in LASCO/C2 on 22 August at 8h36 travels mainly southward and will likely miss the Earth. C-class flaring is expected to continue for the next 24 hours. Solar wind speed as observed by ACE is around 500 km/s. The magnitude of the interplanetary magnetic field is near 5 nT, with a mainly negative Bz component. Current geomagnetic conditions are unsettled. A new increase to active levels is predicted later today due to the arrival of the CME of 20 August. On 24 and 25 August we expect active to minor storm levels (K possibly up to 5) due to the arrival of the CME of 21 August, combined with some minor influence of a coronal hole fast speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 094, gebaseerd op 14 stations.
