Solar activity was low. A C7/Sf flare was observed from Region 1428 (S17W19). Region 1429 (N17E01) remains a large Ekc spot group with a Beta-Gamma-Delta magnetic classification. Possible separation was observed within the intermediate area of the spot group.

Solar activity is expected to continue at low to moderate levels with a chance for further X-class activity from Region 1429 for the next three days (09 - 11 March).

The geomagnetic field ranged from quiet to minor storm conditions with major storm periods observed at high latitudes during 08/1200 - 1800Z. At 08/1045Z, a 40 nT shock was observed at the ACE spacecraft from the arrival of the coronal mass ejection (CME) associated with the X5 flare that occurred early on 07 March. A sudden impulse was observed shortly after at the Boulder magnetometer at 08/1105Z (59 nT). Minor storm periods were observed as a result of the CME arrival. The greater than 10 MeV proton event that began at 07/0510Z increased to a maximum of 6530 pfu at 08/1115Z as a result of the CME shock. The greater than 100 MeV proton event that began at 07/0405Z, and reached a maximum value of 69.3 pfu at 07/1525Z, has slowly declined.

The geomagnetic field is expected to be unsettled to active with isolated minor to major storm periods possible on day 1 (09 March) as the Earth continues to be under the influence of the CME from 07 March. Quiet to unsettled conditions with isolated active periods possible are expected for days 2 - 3 (10 - 11 March).
