Bulletin
Only C-class flares in past 24h, more are expected. The strongest was a C2.9 at 08:40 UT from NOAA AR 1868. NOAA AR 1875 has a beta-gamma configuration and could produce M-class flares. Geomangetic conditions have been quiet and are expected to remain so. There are small probabilities that the fast solar wind from a coronal hole at high northern latitudes, and the effects of the halo CME from October 16 could affect geomagnetic conditions in the next 48h.
