SDF Number 318 Issued at 2200Z on 14 Nov 2005 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was at moderate levels. Region 822 (S06E55) produced two M-class flares: an M2.6 flare at 0421 UTC and an M3.9 flare at 1423 UTC. A Type II radio sweep was observed in association with the M3.9 flare. Region 822 is a magnetic beta-gamma spot group and has grown over the past 24 hours. The remainder of the disk was spotless.
IB. Solar Activity Forecast
Solar activity is expected to be at moderate levels. If the region continues to grow, there is a possibility for major flare activity.
