Solar activity was at high levels. Region 9715 (N05E17) produced a major flare during the period. This impulsive M6/1b event peaked at 28/1635 UTC, and was associated with a Type II radio sweep that had an estimated shock velocity of 674 km/s, a Type IV radio sweep, and a 450 pfu tenflare. This event also produced a partial halo CME based on SOHO/LASCO imagery. Other notable flares from this region were an M2/1f flare at 27/2121 UTC and a C7 x-ray flare (optically correlated using SXI imagery) at 28/1543 UTC with an associated Type II radio sweep that had an estimated shock velocity of 889 km/s. Region 9715 continues to show significant growth as evidenced by a delta configuration magnetic classification that has become evident during the period. Four new regions were numbered today, Regions 9718 (S07E70), 9719 (N03E03), 9720 (S18E72), and 9721 (N10E78).

Solar activity is expected to be at moderate to high levels.

The geomagnetic field was at quiet to unsettled levels. The greater than 10 MeV proton event that began on 22/2320 UTC, ended at 28/2100 UTC (max pfu of 18,900 occurred at 24/0555 UTC).

The geomagnetic field is expected to be at quiet to unsettled levels through most of the forecast period. The partial halo CME from the M6/1b (mentioned in 1A above) is expected to pass late on day three with brief minor storming periods possible.
