Solar Forecast

23 Oct 24 Oct 25 Oct Activity Moderate to high Moderate Moderate Fadeouts Probable Possible Possible 10.7cm/SSN 215/165 220/170 220/170 COMMENT: A number of C-class flares as well as the listed events. AR 12192 (S13E12) continues to grow and produced the X1, M8 and M2 flares while the M1 originated from over the east limb. AR 12193 (N05W29) has also shown growth. The other three spot groups are stable. LASCO images show CMEs associated with the M8 and M2 events but these appear directed out of the ecliptic plane. There appears to be a minor ejection related to the X flare towards the east. The solar wind speed declined from a peak of ~600 km/s to ~450 km/s with the north-south IMF range +/-5 nT. The leading edge of a recurrent coronal hole is located at 56 degrees west and should become geo-effective on 23 Oct.
