Solar activity was at low levels as only low level C-class and optical
subflares were observed during the past 24 hours. Region 1998 (S10E58,
Cao/beta) produced a C1/Sf flare at 06/0925 UTC, along with an
associated Type II radio sweep (estimated shock speed 495 km/s). Region
1990 (S12W48, Dso/beta), Region 1993 (N16W44, Bxo/beta), and Region 1996
(N15E09, Cso/beta) each produced low levels C-class flares as well.
There was slight redevelopment visible in the leader spots of Region
1990, and growth in the intermediate spots of Region 1999 (S18E14,
Dao/beta). The remaining spot groups were either stable or exhibited
signs of decay. A full halo coronal mass ejection (CME), observed near
the beginning of period, originated from a backsided flare that was
visible in NASA STEREO A/B EUVI 195 images at 05/1325 UTC. A couple of
smaller, more narrow CMEs were also observed in Lasco imagery, but were
deemed to be limb or backsided events as well. No Earth-directed CMEs
were observed during the period.
