Solar activity was moderate. A very gradual rise in X-rays began at 03/1545Z, peaking at the M1 level at 03/1716Z and ending at 1737Z. A long duration M2 event soon followed, peaking at 03/1841Z. No obvious optical source was apparent for either event. A C9 flare occurred at 03/0158Z associated with a Type II sweep and bright surge near S22 on the east limb. Region 9591 (S18W81) maintains a Delta configuration as it nears the west limb. New spot groups emerging just east of Region 9591 may add to this region's complexity. Region 9601 (N14W06) continues to maintain moderate complexity with near 700 millionths of white light area coverage and was the source of a number of small C-class flares. New Regions 9604 (S21W61), 9605 (S20E53), and 9606 (S17E57) were numbered today.

Solar activity is expected to be moderate to high. Regions 9591 and 9601 maintain good potential for M-class flares and an isolated major flare. New spot development just east of Region 9591 further supports potential for significant activity near the SW limb. Activity on the SE limb suggests a region with some complexity will rotate into view the next day or so.

The geomagnetic field was at quiet to minor storm levels. A high speed coronal hole stream and possibly some weak CME effects are producing the disturbed conditions.

The geomagnetic field is expected to be unsettled to active through day one with isolated high latitude minor storm periods. Conditions will return to quiet to unsettled levels by days two and three.
