Bulletin

Solar activity has been moderate, many C-class flares were detected from AR 1865, 1861. NOAA AR 1865 produced an M1.3 flare with peak time at 23:36 UT on October 15, no CME was associated with this flare. More M-class flares can be expected from these two active regions. The CME associated with the M1.8 flare from yesterday peaking at 08:38 UT is not expected to arrive to the Earth. Geomagnetic conditions have ranged from quiet to unsettled due to the fast speed stream from a coronal hole. The solar wind speed is currently at 480 km/s and the magnetic field intensity around 4 nT. We expect quiet conditions, except for the possible arrival (estimated probability of 30%) of the CME from October 13 that could raise the geomagnetic conditions up to storm levels late today.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 092, gebaseerd op 09 stations.
