Solar Activity
Solar activity remained at low levels. Region 4105 (S14E34, Eai/beta-gamma) remained the largest, most magnetically complex and productive region. It produced the largest flare of the period, a C4.5 flare at 06/1702 UTC. The region of emerging flux in the SE quadrant (S17E10) was assigned active region number 4107, and was initially classified as a Cro/Beta type. The remaining numbered regions were steady or decaying. Emerging flux was noted in a few areas scattered around the visible disk, but at the time of this writing, none were persistent enough to warrant numbering. CMEs were observed emerging from the south and northeast (06/1112 UTC in LASCO/C2) during the period. Neither was judged geoeffective.
Solar Wind
Solar wind parameters were quiescent. Total magnetic field strength was mostly at or below 5 nT, with Bz generally +/-4. Solar wind speed was steadily decreasing from 500-400 km/s. Phi angle was mostly negative.
Energetic Particle
The greater than 2 MeV electron flux reached high levels with a peak flux of 5,178 pfu observed at 06/1615 UTC. The greater than 10 MeV proton flux was near background levels.
