Bulletin

Two C-class and one M-class flares were observed in the past 24 hours. A C7.4 flare originated from Catania sunspot region 16 (NOAA AR 2113) peaking at 21:13 UT on July 10, almost immediately followed by an impulsive M1.5 flare from Catania sunspot region 5 (NOAA AR 2106). The CME of July 10 has further extended to an asymmetric halo CME, but is propagating mainly west of the Sun-Earth line. No additional Earth- affecting CMEs were identified. Flaring activity is expected to continue at the level of C-class flares, with a slight chance for an isolated M-class flare. Solar wind speed is near 400 km/s, as measured by ACE. The magnitude of interplanetary magnetic field was stable with values near 5 nT with a Bz component fluctuating between -4 and +4 nT. Geomagnetic conditions have been quiet to unsettled and are expected to remain so till the possible arrival of a glancing blow July 8 CME. Active conditions are expected on the UT evening of July 11. Active conditions are also possible on the UT morning of July 13, due to the arrival of a glancing blow of the July 9 CME.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 112, gebaseerd op 09 stations.
