Solar Activity
Solar activity declined to low levels this period with only C-class flare activity observed. Region 3654 (S08W16, Ehi/beta-gamma) remained the largest region on the disk and exhibited moderate development in the intermediate and trailer spots. Region 3657 (S15W25, Bxo/beta) reemerged with a few rudimentary spots and new Region 3660 (N10E71, Axx/alpha) was numbered. The remaining regions were either stable or in decay. No Earth-directed CMEs were detected in available imagery.
Solar Wind
The solar wind environment was enhanced due to likely CME activity early in the period, followed by the onset of positive polarity CH HSS influences. Total field strength reached a peak of 17 nT and the Bz component was sustained southward through the first half of the period, with a peak deflection of -11 nT observed. During the latter half of the period, the Bz component rotated northward with only brief southward deflections observed. Solar wind speeds were steady between 300-350 km/s until 27/0230 UTC, when speed values slowly increased to a period high of around 550 km/s. The phi angle transitioned from negative to positive at 26/1502 UTC.
Energetic Particle
The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was steady at background levels.
