Bulletin

There were one M flare and fourteen C flares on the Sun during the past 24 hours. The M1.0 flare was released by NOAA AR 11875 and peaked at 00:22 UT on October 22. AR 11875 has now become a beta-gamma-delta region, and produced all but one of the fourteen flares. More M flares are likely from this region within the next 48 hours, with a slight chance for an X flare. Solar wind speed rose slightly from 290 to 330 km/s within the last 24 hours. In the same period, the Interplanetary Magnetic Field increased from about 3 nT to about 8 nT. These increases are possibly related to the arrival of a weak coronal hole high speed stream. Solar wind speeds are expected to stay nominal from October 22 till 24. LASCO C2 observed a CME around 1:48 UT on October 22, probably associated with the M1.0 flare. Evaluation of the available imagery from LASCO C2 and STEREO COR2 A and B suggests that this CME is not Earth-directed. Geomagnetic activity was at quiet levels (K Dourbes between 0 and 3; NOAA Kp between 0 and 3) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for October 22 till 24.
