22nd October

Solar activity was low. Regions 1875 (N06E19, Ekc/beta-gamma-delta) and 1877 (S13E38, Cho/beta) were the most notable regions on the disk, and the most active. the largest event of the period was a C2/Sf, produced by Region 1875 at 21/2311 UTC. Additional analysis of the previously reported CMEs from 20 Oct suggests that two filament eruption-related events occurred during the past 36 hrs, both of which had potential for modest geoeffectiveness. Speed measurements of about 650 km/s and 430 km/s, respectively, were observed with the CMEs.
