Solar Activity
Solar activity was at low levels with a few weak C-class flares that originated from beyond the ESE limb. Region 4122 (N13E03, Dso/beta) remains the largest region, but appears to be generally stable with no significant growth. Growth was observed in Region 4123 (S28W09, Cro/beta) and newly numbered Regions 4127 (S18E34, Cro/beta) and 4128 (S05E40, Dao/beta). All other regions were mainly quiet or in slight decay.
Solar Wind
Solar wind parameters reflected weakening negative polarity CH HSS influence. Total field averaged 4-6 nT. The Bz component underwent several southward deflections reaching a maximum of -5 nT. Solar wind speeds slowly decreased through the period from about 550 km/s to near 450 km/s. The Phi angle was in a predominantly negative solar sector.
Energetic Particle
The greater than 2 MeV electron flux reached high levels with a peak flux of 6,349 pfu observed at 29/1600 UTC. The greater than 10 MeV proton flux was at background levels.
