Solar activity was low. Several low, optically uncorrelated C-class flares were observed, the largest being a C4 at 29/0940Z. The likely sources for most of the discrete X-ray bursts were Regions 9915 (N12W53) and 9919 (N15W13). No appreciable changes were noted in these or the remaining active regions on the visible disk. The overall enhanced X-ray baseline is likely due to the return of several active regions on or near the east limb. Considerable CME activity was noted off the east limb over the past 24 hours. New Regions 9927 (S28E68), and 9928 (N18E75) were numbered today.

Solar activity is expected to be low. Continued C-class flares are likely from Regions 9915 and 9919. The potential for activity at or near the east limb will increase over the coming days.

The geomagnetic field was quiet to unsettled with isolated active periods at high latitudes. The disturbed conditions are due to a high speed coronal hole stream that began on the 27th.

The geomagnetic field is expect to continue at quiet to unsettled levels with isolated active periods at high latitudes.
