Solar Activity-brief .24 hr Summary... Solar activity was at moderate levels (NOAA Scale R1-Minor) during the past 24 hours. Region 1890 (S11E17, Ekc/beta-gamma-delta) was responsible for the largest event of the period, an impulsive M3/1n flare at 06/1346 UTC with an associated Type II radio sweep (estimated velocity of 586 km/s). Region 1890 also produced an impulsive M2 flare at 07/0340 UTC with an associated Type II radio sweep (estimated velocity of 603 km/s). A region from around the western limb produced an M1 flare at 07/0002 UTC. An associated coronal mass ejection (CME) was observed in LASCO/C2 imagery at 07/0000 UTC but is not anticipated to be geoeffective based on the source locations position around the western limb. Region 1889 (S18W37, Dao/beta) was responsible for a C3/Sf flare at 06/1731 UTC and showed signs of decay. Region 1891 (S18W18, Dac/beta-gamma) produced a C3/Sf at 07/0211 UTC and showed signs of growth and increased magnetic complexity. There were no Earth-directed CMEs detected in satellite imagery during the period. .Forecast... Solar activity is expected to be low with a chance for isolated M-class activity (R1-Minor to R2-Moderate) and a slight chance for X-class activity (R3-Strong) for the next three days (07-09 Nov) as Region 1890 maintains its complex magnetic structure.
