Solar activity was at moderate levels. Region 9899 (N18E33) produced an M2/2b flare at 09/0042 UTC with an associated Type II radio sweep that had an estimated shock velocity of 552 km/s. The CME activity associated with this event did not appear to be earth-directed in SOHO/LASCO imagery. This region continues to show slow growth in magnetic complexity, evidenced by the addition of satellite spots and penumbral development. An M1 x-ray flare occurred at 09/1302 UTC that went optically uncorrelated. Region 9893 (N19W00) was again, quiescent today, showing no significant activity or appreciable changes from yesterday. However, the delta magnetic spot in this region remains intact. Region 9887 (N04W82) didn't produce any optically correlated flare activity today although an eruptive prominence on the leading edge of region occurred at 09/0720 UTC. This region appears to be in decay as it exits the disk. New region 9904 (S16W07) was numbered today.

Solar activity is expected to be at moderate levels.

The geomagnetic field activity was at quiet levels. The greater than 10 MeV electron flux remains slightly elevated, although well below event threshold.

The geomagnetic field activity is expected to be predominantly at quiet levels through the forecast period. A slight chance of isolated active periods exists late on day three of the forecast period, due to the possibility of some flanking shock effects from the CME mentioned in IA.
