Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: 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 06/2315Z from Region 3738 (S09E58). There are currently 9 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 (08 Jul, 09 Jul, 10 Jul). IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic field has been at quiet to unsettled levels for the past 24 hours. Solar wind speed reached a peak of 412 km/s at 07/1409Z. Total IMF reached 8 nT at 07/1651Z. The maximum southward component of Bz reached -5 nT at 07/1943Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 148 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (08 Jul), quiet to unsettled levels on day two (09 Jul) and quiet levels on day three (10 Jul).
