Catania sunspot regions 6 and 9 (NOAA 2108 and 2109 respectively) are still the largest and most complex regions on the solar disk. However Catania region 16 (NOAA AR 2113) has also grown, developed to a beta-gamma region and was most active during the past period. Two M-class and five C-class flares were detected by GOES X-ray. A M1.2 flare, peaking at 00:26 UT on July 9, and an M6.5 flare, peaking at 16:20 UT on July 8, originated from Catania region 16. The M6.5-flare was associated with dimming, type II and IV radio bursts and a partial halo CME. The CME was first seen in the SOHO/LASCO C2 field of view at 16:36 UT, had an angular width of 126 degrees and a projected plane of the sky speed of 466 km/s (as reported by the CACTus software). The bulk of the CME mass was ejected east from the Sun-Earth line. The arrival of a glancing blow from the CME-driven shock wave is possible in the evening of July 11. Flaring activity is expected to continue with C-class flares and possibly an isolated M-class flare. Solar wind speed is stable near 350 km/s, as measured by ACE. The magnitude of interplanetary magnetic field obtained values between 3 and 8 nT with a mainly negative Bz component. Geomagnetic conditions have been quiet to unsettled and are expected to remain so until the arrival of a fast speed stream that may result in active conditions within the next 24 hours.
Today's estimated international sunspot number (ISN): 124, based on 09 stations.
