Solar activity has been very high. Region 375 (N12W46) produced major flare activity including an X1.7 event at 09/2139 UTC with an associated Type II radio sweep and was optically correlated with SXI imagery. The region also produced numerous M-class flares including an M5.1/2n flare at 10/1112 UTC, and an M5.6/Sf flare at 10/1815 UTC. Region 375 continued its rapid growth over the period (an increase to 1200 millionths), and maintains its delta magnetic configuration. Region 380 (S15E29) increased in magnetic complexity to a beta-gamma-delta configuration. An optically uncorrelated Type IV radio sweep was observed at 0014 UTC. LASCO imagery observed a partial-halo CME beginning at 10/0606 UTC, most likely associated with former Region 365 (S07,L=182) on the back side of the sun. New Region 382 (S18W17) was numbered today.

Solar activity is expected to be moderate to high. Regions 375 and 380 both remain capable of producing a major flare.

The geomagnetic field has been at unsettled to minor storm levels. This activity is due to continued coronal hole high speed stream effects. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.

The geomagnetic field is expected to be unsettled to active with isolated periods of minor storm conditions through day one. Quiet to unsettled conditions are expected for days two and three as solar wind speeds are expected to decrease.
