We expect essentially quiet conditions for the solar activity with a risk for an isolated C class flare from NOAA AR 1856. It produced on October 7 a C6.2 flare, peaking at 0414 UT. Current coronagraphic observations do not show a CME related to this event, but data are scarce and this will be checked in the coming hours. A C1.1 flare occurred on October 6, in Catania region 95, east of NOAA AR 1859. Peaking at 1424 UT, it was associated with a dimming and a faint halo CME observed in LASCO C2. This event might have a weak effect on the geomagnetic activity, triggering active conditions by the end of Oct. 10. For the current 48 hours, the geomagnetic activity is expected to remain mostly quiet with possibly an isolated period of unsettled conditions. Current ACE observations show weak excursions of the Bz component of the magnetic field down to -5 nT, corresponding to a sector boundary crossing.
Today's estimated international sunspot number (ISN): 053, based on 15 stations.
