There were five C flares on the Sun during the past 24 hours. The brightest one was a C2.0 flare from NOAA AR 11868 peaking at 12:45 UT on October 20. More C flares are expected within the next 48 hours, with a fair chance for an M flare from beta-gamma region NOAA AR 11875, which features strong flux emergence at present. Solar wind speed was nominal and varied between 280 and 360 km/s within the last 24 hours. In the same period, the Interplanetary Magnetic Field was in the range from 2 to 5 nT. Solar wind speeds are expected to increase slightly on October 21 and 22 under the influence of an expected weak coronal hole high speed stream. Geomagnetic activity was at quiet levels (K Dourbes between 0 and 3; NOAA Kp between 0 and 1) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for October 21 till 23, with a chance for active periods due to an expected weak coronal hole high speed stream.
