Solar Activity
Solar flare activity has been at low levels. There have been five C-class flares with most of the activity coming from newly numbered Region 3916 (S16E72, Cai/beta). Region 3906 (S16W76, Eko/beta-gamma) and Region 3912 (S05E11, Eai/beta) both produced C-class flares, the largest being a C6.1 at 03/0544 UTC from Region 3906. There have been no Earth-directed CMEs observed in available coronagraph imagery.
Solar Wind
Solar wind parameters reflected the arrival of a weak CME early in the period and have been enhanced since. Total magnetic field was between 12-14 nT early on and has remained around 10 nT for most of the period. The Bz component varied between -7 and 12 nT. Solar wind speeds have averaged around 420 km/s. The phi angle has been mostly positive (away from the Sun) but has had three transitions into the negative for about 2-4 hours at a time.
Energetic Particle
The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux remained at background levels.
