Solar Activity

.24 hr Summary...
Solar activity reached moderate levels, R1 (Minor), following an
isolated M1/1n flare recorded at 20/1122 UTC from Region 3102
(S26W26, Eko/beta). At 20/1503 UTC, the region produced a long duration
C7.7/1f event. The optical flare associated with this event displayed a
ribbon characteristic. The region continued to show consolidation in the
southern portion of the trailer spots, some slight area decay and
magnetic simplification.

Region 3105 (S14E62, Dhi/beta) continued to rotate into view showing
more spots and added complexity. Despite its size and complexity, the
region has remained relatively quiet. This new spot group is likely the
return of old Region 3089 (S23, L=197). New Region 3106 (S10E56,
Bxo/beta) was numbered during the period. This small bi-polar group was
included in Region 3105 and is located just to the NW of the main body
of spots. Its apparent, based on magnetic observations, that its a
separate group. Additional spots are currently rotating onto the disk to
the SE of Region 3105 that appear to be a new group.

Region 3100 (S22W86, Hax/alpha) began to simplify and consolidate as it
rotated around the western limb. Newly numbered Region 3104 (S11, L=350)
decayed to plage.

No Earth-directed CMEs were detected in available coronagraph imagery.

.Forecast...
Solar activity is expected to be low with a chance for M-class
(R1-R2, Minor-Moderate) flares on 21-23 Sep. The chance for elevated
activity is due primarily to the flare potential of Regions 3102 and
3105.
