Solar Activity
Solar activity declined to low levels. Regions 3638 (S18, L=231), 3639 (N30W90, Axx/alpha) and 3647 (S13, L=217) produced C-class flare activity during the period, the largest a C6.6 at 26/0636 UTC from Region 3639. Region 3654 (S08W08, Eai/beta-gamma) remained the largest region on the disk, but was quiet. The region did indicate some slight area decay. Minor development was observed in Region 3658 (S23W60, Dro/beta). The remaining regions were either stable or in decay. No Earth-directed CMEs were detected in available imagery.
Solar Wind
Solar wind conditions became weakly enhanced at around 26/0018 UTC. Total magnetic field strength reached a peak of 13 nT at 26/1510 UTC, while the Bz component was sustained southward most of the period, by as much as -11 nT 26/1250 UTC. Solar wind speed peaked at 387 km/s at 26/0116 UTC and slowly decreased to low speeds near 305 km/s near the end of the period. The phi angle was predominately negative through about 26/1500 UTC when the orientation switched to positive.
Energetic Particle
The greater than 2 MeV electron flux was at normal to moderate levels, while the greater than 10 MeV proton flux was steady at background levels.
