Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 9 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 (06 Jul, 07 Jul, 08 Jul). IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field has been at quiet to major storm levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 593 km/s at 04/2151Z. Total IMF reached 15 nT at 05/0040Z. The maximum southward component of Bz reached -14 nT at 05/0009Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (06 Jul) and quiet levels on days two and three (07 Jul, 08 Jul). III.
