Solar Activity
Solar activity was at low levels. Only C1-level X-ray events were observed. Newly numbered Region 4159 (S08W10, Cro/beta) increased the numbered of spotted numbered active regions on the visible disk to nine. Despite numerous sunspots, all regions remained relatively simple and quiet. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is likely to be low with a chance for M-class flares (R1-R2/Minor-Moderate) over 26-28 July.
Solar Wind
The solar wind environment was suggested continued influence from negative polarity coronal hole. Total field ranged from 4-10 nT. No significant southward periods of the Bz component were observed. Solar wind speeds varied from ~480-600 km/s. The phi angle was in a predominately negative orientation.
Energetic Particle
The greater than 2 MeV electron reached high levels with a peak flux of 3,123 pfu at 25/1640 UTC. The greater than 10 MeV proton flux was steady at background levels throughout the period.
