Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 5 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 (11 Jul, 12 Jul, 13 Jul). IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 428 km/s at 09/2134Z. Total IMF reached 5 nT at 10/2058Z. The maximum southward component of Bz reached -3 nT at 10/0302Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 3114 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one and three (11 Jul, 13 Jul) and quiet to unsettled levels on day two (12 Jul). III.
