Solar activity was moderate. A long duration M1.0 flare occurred during 07/1114-1143-1317 UTC. Imagery from SOHO/LASCO revealed a fast partial halo CME off the southwest limb in association with this event, possibly from old Region 17 (S18, L=235) behind the west limb. This event also caused an enhancement in energetic protons (see section IIA below). Other activity included a multi-peak C-class event with maximum flux of C3.5 at 07/0401 UTC. H-alpha imagery from the IPS Culgoora observatory revealed an active prominence on the southwest limb as well as plage brightening in Region 19 (S19W32) in association with this event. Another event of interest occurred at about 07/1700 UTC, with a large, 35-degree filament eruption centered near N11W49, which also produced a CME visible in SOHO/LASCO imagery. New Region 27 (S15E26) was numbered today.

Solar activity is expected to be low to moderate. Region 19 remains a potential source of M-class flare activity.

The geomagnetic field was predominantly quiet to unsettled, with one isolated active period observed at Boulder during 07/1500-1800 UTC. Coronal hole effects appeared to wane throughout the day. A 10 MeV proton event began at 07/1830 UTC, due to enhanced flux following the LDE discussed in section 1A above, and remains in progress. Maximum flux observed thus far was 22 pfu at 07/1955 UTC.

The geomagnetic field is expected to be mainly quiet to unsettled. Isolated active periods are possible during the next 3 days, in response to earlier CME activity from Region 19 as well as from the filament eruption and other flare activity observed today.
