Solar Activity
Solar activity returned to moderate levels with two M-class flares observed. The first, an impulsive M1.6/1n flare at 22/1546 UTC, was from Region 3905 (S09E64, Dao/beta-gamma). This region added several low-to-mid-level C-class flares as it rotated further onto the visible disk.
Solar Wind
Solar wind parameters reflected weak, negative polarity CH HSS influence. Solar wind speeds were between 370-430 km/s, total field strength averaged near 8 nT, and the Bz component fluctuated between +/-8 nT. The phi angle was predominantly in a negative position, with occasional oscillations into a positive orientation the first half of the period.
Energetic Particle
The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux reached S2 (Moderate) levels, reached a peak value of 125 pfu at 22/0355 UTC, and decreased below the S1 (Minor) threshold at 22/1845 UTC. The 100 MeV proton levels reached a peak value of 7 pfu at 21/2010 UTC, but have since decreased well below the 1 pfu SWPC warning threshold.
