Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: 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 on days one, two, and three (16 Jun, 17 Jun, 18 Jun). IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 377 km/s at 15/1101Z. Total IMF reached 5 nT at 15/0256Z. The maximum southward component of Bz reached -4 nT at 15/0819Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 145 pfu. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (16 Jun, 17 Jun) and quiet levels on day three (18 Jun). III.
