Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 8 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (02 Aug, 03 Aug, 04 Aug). IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 558 km/s at 01/0611Z. Total IMF reached 8 nT at 01/2059Z. The maximum southward component of Bz reached -7 nT at 01/2018Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1386 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (02 Aug) and quiet levels on days two and three (03 Aug, 04 Aug). III.
