Solar activity remained at low levels today. Regions 536 (S12W54) and 537 (N05E11) produced lesser B and C-class flares today. Region 536 continues to show steady decay. The beta-gamma magnetic structure remains evident. Region 537 has changed little since yesterday, a few satellite spots in the eastern most portion of the cluster have vanished during the period. A slight counter-clockwise rotation in the spot group is evident in white light analysis. The beta-gamma/delta magnetic complex remains intact. CME activity was seen on SOHO/LASCO imagery emanating from just beyond the solar northeast limb, in the vicinity of where old Region 528 is due to return on 14 January. SXI imagery indicates potential for an active region beyond the solar southeast limb as coronal surging has been common place through much of the period.

Solar activity is expected to be at low to moderate levels. A slight chance for an isolated major flare still exists due to the magnetic complexity of both Regions 536 and 537.

The geomagnetic field was at quiet to active levels. A favorably positioned coronal hole high speed stream continues to enhance field conditions. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels again today.

The geomagnetic field is expected to be a quiet to active levels. Periods of isolated minor storming are possible in nighttime sectors of high latitudes. The geoeffective coronal hole should start to wane by 13 January with predominantly quiet to unsettled conditions to follow.
