Solar activity was low. Region 1543 (N22W19) produced the largest event of the period, a C3/Sf flare at 14/0031Z. An Earth-directed, partial-halo CME was subsequently observed in SOHO/LASCO C3 coronagraph imagery beginning at 14/0130Z with an estimated plane-of-sky speed of 436 km/s. An additional Earth-directed, partial halo CME was observed in SOHO/LASCO C2 coronagraph imagery beginning at 13/1325Z with an estimated plane-of-sky speed of 606 km/s. This CME was associated with a C2 flare at 13/1240Z with associated Type II (estimated velocity of 736 km/s) and Type IV radio sweeps from Region 1543. Region 1543 showed little change and maintained a beta-gamma magnetic configuration. The remaining spotted regions were stable and quiet.

Solar activity is expected to be low with a slight chance for an isolated M-class flare.

The geomagnetic field was quiet to unsettled.

The geomagnetic field is expected to be mostly quiet on day 1 (15 August). Quiet to unsettled levels with a slight chance for active conditions are expected on Day 2 (16 August) due to effects from the 13 August CME. Unsettled to active levels with a slight chance for minor storm conditions are expected on Day 3 (17 August) due to effects from the 14 August CME.
