Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 2 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low on days one, two, and three (12 Jul, 13 Jul, 14 Jul). IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 444 km/s at 10/2335Z. Total IMF reached 5 nT at 10/2142Z. The maximum southward component of Bz reached -3 nT at 11/1311Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 159 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on days one, two, and three (12 Jul, 13 Jul, 14 Jul). III.
