There was only one C flare on the Sun during the past 24 hours, originating from Catania sunspot region 29 (NOAA active region 11884). The X-ray background level has been reduced to the B-level. For the next 48 hours, M flares are expected. No Earth directed CMEs were observed. The proton flux measured by GOES is currently decreasing. Solar wind speed reached a maximum of 400 km/s as observed by ACE. The magnitude of the interplanetary magnetic field (IMF) increased from 6 to 12 nT, mainly with a positive Bz component. Geomagnetic activity is quiet to unsettled (local K at Dourbes and NOAA Kp between 0 and 3). Unsettled to minor storm conditions (K= 3 to 5) are possible within the next 48 hours, due to weak effects of the CMEs that erupted on October 28.
Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 089, sur la base de 16 stations.
