Solar activity was at very low levels. The largest event was a B9.2 X-ray enhancement at 14/1825 UTC. The most likely source of this enhancement was a disappearing solar filament that lifted off near S25W55. The western most 30 degrees of the large filament lifted off at 14/1730 UTC and was associated with a CME, as seen in LASCO imagery. There is not enough data at the time of this report to determine if the CME will be geo-effective. Two other DSFs occurred during the past twenty-four hours. A 10 degree filament lifted off near S16W27 at 13/2030 UTC and a 13 degree filament lifted off near N40E45 at 13/2200 UTC. The 13 degree DSF was associated with a CME off the northeast limb but does not appear to be Earth directed. New Region 314 (S14E00) rapidly appeared on the visible disk and grew to 80 millionths. Magnetic complexity of Region 314 also rapidly increased to a beta-gamma configuration.

Solar activity is expected to be at low levels. Regions 306 (N07W19) and 314 have C-class potential and a slight chance for M-class events.

The geomagnetic field was at quiet to active levels. Early in the period solar wind velocity increased to over 600 km/s marking the onset of the expected high speed stream. Fluctuations in the Bz component of the interplanetary magnetic field to -8 nT resulted in isolated active conditions.

The geomagnetic field is expected to be at quiet to active levels with isolated minor storm levels possible. High speed stream effects are expected to continue through the forecast period.
