Analysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low on days one, two, and three (22 Jul, 23 Jul, 24 Jul). IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 368 km/s at 21/1035Z. Total IMF reached 5 nT at 21/0820Z. The maximum southward component of Bz reached -3 nT at 21/0305Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 268 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on day one (22 Jul) and quiet to unsettled levels on days two and three (23 Jul, 24 Jul). III.
