Solar activity has been high. Region 375 (N10W62) produced major flare activity including an X1.3/2b at 11/0002 UTC and an X1.6/1n at 11/2015 UTC. Region 375 maintained its size and magnetic complexity. Region 380 produced an M1.8/1f at 11/1743 UTC. At 11/1730 UTC a filament near S37E12 erupted and was observed on SOHO/EIT and Mauna Loa H-alpha. Background X-ray flux remained at M levels for 6 hours during the period beginning at about 1300 UTC. New Region 383 (N19E22) was numbered today.

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

The geomagnetic field has been at unsettled to active levels, due to continued effects from a coronal hole high speed stream. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today.

The geomagnetic field is expected to be unsettled to active through day one, with isolated periods of minor storm conditions possible due to CME arrival from yesterday's flare activity. Unsettled conditions are expected on days two and three as the coronal hole wind stream moves out of geoeffective position. Active conditions are possible on day three due to potential effects of CMEs related to the major flares and erupting filament observed today.
