Solar activity has been low. Several C-class events occurred, the largest being a C9.7 flare at 01/0012 UTC. No corresponding optical flare report was received for this event, but SOHO/EIT imagery suggests that Region 9845 (N17W04) was the source. Two type-II radio sweep events occurred during the period. The first was at 01/0214 UTC, with an estimated velocity of 1200 km/s. SOHO/LASCO imagery revealed a fast CME from a source behind the southwest limb at this time, though not appearing earth-directed. The second sweep had an estimated velocity of 742 km/s and occurred at 01/0542 UTC, shortly after an impulsive C7/Sf from Region 9848 (S20W21) at 01/0531 UTC. However, no CME activity was evident in LASCO imagery following this event. Two new regions were numbered today: 9851 (S07E56), and 9852 (N16E66).

Solar activity is expected to be low to moderate for the next three days. Region 9845 is a possible source for isolated M-class flares.

Geomagnetic field activity was at quiet to minor storm levels. A sustained period of southward IMF, following a weak interplanetary shock passage early on 28 February, caused active and isolated minor storm conditions at higher latitudes during 28/2100 - 01/0300 UTC. Activity has been predominantly quiet since then.

Geomagnetic field activity is expected to be mainly quiet to unsettled, until the onset of high speed stream effects from a recurrent coronal hole begin to develop by day three of the forecast period. Isolated active conditions are anticipated thereafter.
