Solar activity reached high levels today. Region 1429 (N18W13) produced an M6 flare at 09/0353Z. Associated with this event was Type II (1285 km/s) and Type IV radio sweeps along with a full halo CME first seen in SOHO/LASCO C2 imagery at 09/0426Z. The CME had an estimated plane-of-sky speed of 850 km/s in STEREO B COR2 imagery. Separation and slight decay within the intermediate area was observed in Region 1429, however it still remained a large Ekc spot group with a Beta-Gamma-Delta magnetic configuration. A new spot group rotated onto the NE limb and was numbered Region 1432 (N18E69). This new region is too close to the limb to accurately determine the spot and magnetic classification, however it produced a C9 flare at 09/2025Z.

Solar activity is expected to continue at low to moderate levels with a chance for X-class activity from Region 1429 for the next three days (10 - 12 March).

The geomagnetic field was at active to severe storm conditions due to continued activity from the sheath region associated with the 07 March CME. At approximately 09/0049Z, the Bz component of the interplanetary magnetic field started to rotate towards a more magnetically connected polarity. Bz continued to be negative for several hours reaching values near -17 nT with an approximate solar wind speed over 600 km/s. The geomagnetic field responded with major to severe storm periods during the periods 09/0300 - 1500Z. Solar wind remained elevated around 600 km/s by the end of the period. The greater than 10 MeV proton event that began at 07/0510Z is ongoing. The greater than 100 MeV proton event that began at 07/0405 is ongoing.

The geomagnetic field is expected to be under the influence of the current CME through early on day 1. Unsettled to active conditions, with isolated minor storm periods, are possible is expected as the CME continues to wane. Early to mid-day on day 2 (11 March), the CME associated with todays M-6 flare is expected to become geoeffective. Active to severe storm periods are expected with this event. Unsettled to active conditions, with isolated minor storm periods, are possible on day 3 (12 March) as conditions are expected to slowly dissipate.
