There were six M flares and eleven C flares on the Sun during the past 24 hours. The brightest one was an M9.3 flare released by NOAA AR 11877 with peak time at 00:30 UT on October 24, and caused a Type II radio burst with estimated shock speed of 750 km/s. All C and M flares were produced either by NOAA AR 11875 or NOAA AR 11877, both of which are beta-gamma-delta regions with rapidly evolving topology. In the next 48 hours, X flares from either region are possible. Since both regions are near the central meridian, there is a substantial risk of halo CMEs and a warning condition for proton storms is issued. In the past 24 hours, solar wind has varied between about 310 and 350 km/s. In the same period, the Interplanetary Magnetic Field has varied between 5 and 8 nT. The M4.2 flare of October 22 was accompanied by a faint halo CME, which could deliver a glancing blow to Earth on October 27. Geomagnetic activity was at quiet levels (K Dourbes between 0 and 3; NOAA Kp between 0 and 1) during the past 24 hours. Active conditions (K Dourbes = 4) with isolated minor storm intervals (K Dourbes = 5) are possible in the second half of October 24 and on October 25, due to a possible glancing blow from the CME from October 22 (observed by LASCO C2 at 4:36 UT). Quiet conditions (K Dourbes < 4) are expected for October 26.
