Solar Activity
Solar activity reached moderate levels. Region 3889 (S10E38) produced an impulsive M4.2 flare (R1/Minor) at 10/0015 UTC; the largest event of the period. The region exhibited some growth around its leader spot. The remaining active regions on the visible disk were either stable or in decay. No Earth-directed CMEs were observed in available coronagraph imagery.
Solar Wind
The solar wind environment remained enhanced this period. Total field strength ranged from 4-13 nT and the Bz reached as far south as -11 nT. Solar wind speeds averaged around 400 km/s throughout the period.
Energetic Particle
The greater than 10 MeV proton flux was at background levels and the greater than 2 MeV electron flux was at normal to moderate levels.
