Bulletin

Seven M-class flares and six C-class flares were counted since the last bulletin. An M3.5 flare was the largest flare, peaking at 1:35 UT, originating from Catania sunspot group 88 (NOAA AR 2192). Catania group 88 is currently located at the west limb and although it is difficult to determine it's characteristics, the region seems to have shrinked. All other regions on the front side of the solar disk were relatively stable. Catania group 88 is still capable to produce large flares, mainly at the M-level, with a minor chance for another X-flare. We retain the warning condition for a proton event. No Earth-directed CMEs were observed in coronagraphic imagery. The solar wind speed observed by ACE is low at around 350 km/s. The interplanetary magnetic field has a magnitude of about 5 nT. A sector boundary crossing is observed at about 08:00 UT on October 30 as the phi angle changed from a mostly positive to negative orientation. Mostly quiet geomagnetic conditions are expected, with a chance for an isolated time slot of active conditions (K=4).

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 080, na základě 11 stanic.
