Solar activity was moderate due to an M1/1n flare at 0507 UTC from Region 537 (N04E50). The group produced additional small flares throughout the day. Analysis of the region indicates a small, relatively compact group of spots with an inversion line running northeast to southwest and cutting through penumbra, making this a delta class group. Region 536 (S10W16) continues to be the largest group and also has a delta configuration. The region produced a few small flares during the past 24 hours and is slowly decaying. A CME was reported by LASCO over the south solar pole, beginning at 1654 UTC on the 7th, and associated with subsequent relatively faint, large scale post-eruption loop system (visible in EIT 195) just to the west and south of Region 536.

Solar activity is expected to be moderate for 09-11 January with Regions 536 and 537 being the most likely source for activity. There continues to be a slight chance for a major flare or proton producing flare from either of these regions during the 09-11 January forecast period.

The geomagnetic field was quiet to unsettled. ACE solar wind showed a steady decline of solar wind velocity and Bz was mostly weak during the past 24 hours. The solar wind appears to be transitioning to nominal conditions, probably indicating the end of the recent high speed stream at ACE. The greater than 2 MeV electron fluxes were high during the past 24 hours.

The geomagnetic field is expected to be generally unsettled for 09-11 January with a slight chance for isolated active periods.
