Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been at very low levels for the past 24 hours. There are currently 0 numbered sunspot regions on the disk. IB. Solar Activity Forecast: Solar activity is expected to be very low on days one, two, and three (12 Jun, 13 Jun, 14 Jun). IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been at quiet to minor storm levels for the past 24 hours. Solar wind speed reached a peak of 435 km/s at 11/1815Z. Total IMF reached 13 nT at 11/1433Z. The maximum southward component of Bz reached -12 nT at 11/1441Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 560 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to active levels on day one (12 Jun) and quiet to unsettled levels on days two and three (13 Jun, 14 Jun). III.
