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. The largest solar event of the period was a C4 event observed at 04/1439Z from Region 2108 (S08E28). There are currently 9 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is likely to be moderate with a slight chance for an X-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 levels for the past 24 hours. Solar wind speed, as measured by the ACE spacecraft, reached a peak speed of 350 km/s at 04/0727Z. Total IMF reached 5 nT at 04/0803Z. The maximum southward component of Bz reached -4 nT at 04/0722Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (05 Jul, 06 Jul) and quiet levels on day three (07 Jul). III.
