Bulletin

Only C-class flares were observed in the past 24h, the strongest was a C8.4 with peak at 15:26 UT on October 18, from NOAA 1861. As this AR (and NOAA 1865) are rotating over the west limb, only C-class flares are expected (but still M-flares remain possible). Geomagnetic conditions have been quiet. There is a coronal hole which influence may reach the Earth in the coming 48h, but it is located probably too much to the north (40 degrees) to become geoeffective.

Today's estimated international sunspot number (ISN): 092, based on 12 stations.
