Bulletin

Solar activity was eruptive during the past 24 hours with one C9.6 class flare originating from Catiana sunspot group 24 (NOAA AR 1785) on July 8 at 1h22 UT. Though this group has reduced in number of sunspots, it's photospheric magnetic field remains to have beta-gamma-delta configuration. It is capable of producing more C-class flares and maybe an M-class flare. No geo-effective CMEs were observed. We are currently under influence of a slow solar wind (speed around 300 km/s). The magnitude of the interplanetary magnetic field is low (about 5 nT). Geomagnetic conditions are quiet and are expected to remain so for the next 48 hours.

Today's estimated international sunspot number (ISN): 078, based on 17 stations.
