Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity has been at low levels for the past 24 hours. There are currently 6 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be low on days one, two, and three (07 Jul, 08 Jul, 09 Jul). IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 510 km/s at 06/0708Z. Total IMF reached 12 nT at 05/2104Z. The maximum southward component of Bz reached -10 nT at 06/1014Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 317 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (07 Jul, 08 Jul) and quiet levels on day three (09 Jul). III.
