Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 0 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (10 Jul, 11 Jul, 12 Jul). IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 452 km/s at 09/0737Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 370 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (10 Jul), quiet to unsettled levels on day two (11 Jul) and quiet levels on day three (12 Jul).
