Analysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: 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 with a slight chance for an M-class flare on days one, two, and three (05 Jul, 06 Jul, 07 Jul). IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 464 km/s at 04/0646Z. Total IMF reached 12 nT at 04/2056Z. The maximum southward component of Bz reached -9 nT at 03/2204Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 477 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (05 Jul, 06 Jul, 07 Jul). III.
