Solar Activity
Solar activity was at low levels. Region 4126 (N07W84, Dro/beta) produced a few low level C-class flares as it began its tranist of the western limb. Region 4132 (S17E42, Axx/alpha) exhibited decay as it produced a low level C-class flare as well. Regions 4127 (S18W09, Dai/beta) and 4129 (N02E09, Cri/beta) continued to grow, developing additional spots and increasing in length. Region 4133 (S17W79, Axx/alpha) was numbered this period, but was otherwise unremarkable. The remaining active regions were relatively stable and quiet. No Earth-directed CMEs were observed in available coronagraph imagery.
Solar Wind
Solar wind parameters reflected a mostly nominal solar wind environment. Total field ranged 2-7 nT and the Bz component was -4 to 2 nT. Solar wind speeds gradually decreased from ~450 km/s to near 360 km/s by the end of the period. Phi was predominantly in the negative solar sector.
Energetic Particle
The greater than 2 MeV electron flux reached high levels with a peak flux of 4,930 pfu observed at 02/1430 UTC. The greater than 10 MeV proton flux was at background levels.
