Solar activity was low. Three C-flares occurred during the past 24 hours, one from Region 1333 (N15W02) and two from Region 1324 (N13W63). Region 1324 showed emergence of new flux during the past 24 hours. Region 1333s growth has slowed considerably and the region is currently a small D-type sunspot group with about 50 millionths in sunspot area. Region 1330 (N08W09) continues to be the largest group on the disk with about 450 millionths area and a beta-gamma magnetic classification, but did not produce any flares. A CME was noted from the northeast limb entering the LASCO C3 field of view around 1254Z on the 27th and was associated with a filament eruption and post eruptive loop arcade in the northeast quadrant. The CME appears to be moving too far north of the ecliptic to be geoeffective. An additional CME was observed off the southwest limb and entered the C3 field of view at 0218Z on the 28th. STEREO coronagraph observations clearly showed that this was a backsided event and therefore the event is not expected to be geoeffective.

Solar activity is expected to be low. There is a slight chance for an isolated M-class event with Regions 1330, 1324, and 1333 the most likely sources.

The geomagnetic field was quiet.

The geomagnetic field is expected to be quiet for the first part of day one (29 October). An increase to unsettled levels with a chance for active periods is expected beginning late on the 29th and continuing through the first and second days (30-31 October). The increase is expected due to a high speed stream from coronal hole.
