28th November

Solar activity was at low levels through the period with Region 2222
(S20E50, Ehc/beta-gamma) producing the majority of the C-class activity.
This region produced the largest flare of the period; a C7/Sf flare at
28/0040 UTC. Slight to moderate growth was observed in Region 2222 as
it continued to rotate onto the disk.

Slight elongation was noted in Region 2219 (N04W28, Eai/beta-gamma).
Region 2221 (N04E49, Dac/beta-gamma) indicated overall growth in area,
particularly in its intermediate spots, and developed some mixed
magnetic polarity within the leader portion of the group. New Region
2224 (S24E35, Bxo/beta) developed on the disk this period. The
remaining regions were stable and indicated little change.

Other activity consisted of a C2 x-ray event recorded at 28/0422 UTC.
The event was associated with a filament eruption observed in GONG and
SDO/AIA 193 and 304 imagery between 28/0415-0500 UTC. The 8 degree long
filament was centered near S18E42, to the NW of Regions 2222 and 2224,
and was observed lifting off the SE portion of the disk. No coronagraph
data was available at the time of this report to determine if there was
an associated CME. Further analysis is ongoing.

Solar activity is expected to be at low levels with an increasing chance
for an M-class flare (R1-R2/Minor-Moderate) during the period (28-30
Nov), particularly from Regions 2219, 2221 and 2222. This is based on
these three region’s magnetic complexity and steady growth.
