Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 1 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low with a slight chance for a C-class flare on days one, two, and three (08 Jun, 09 Jun, 10 Jun). 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 576 km/s at 06/2135Z. Total IMF reached 8 nT at 07/0506Z. The maximum southward component of Bz reached -4 nT at 07/0317Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1495 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (08 Jun, 10 Jun) and quiet levels on day two (09 Jun). III.
