Analysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M1 event observed at 04/2005Z from Region 3730 (S18W85). There are currently 7 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 (05 Jul, 06 Jul, 07 Jul). IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 394 km/s at 03/2221Z. Total IMF reached 10 nT at 04/1911Z. The maximum southward component of Bz reached -9 nT at 04/1810Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 792 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on day one (05 Jul) and quiet levels on days two and three (06 Jul, 07 Jul). III.
