Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 163 Issued at 2200Z on 12 Jun 2021

IA.  Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: 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 (13 Jun, 14 Jun, 15 Jun).

IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 467 km/s at 12/2100Z. Total IMF reached 9
nT at 12/0624Z. The maximum southward component of Bz reached -7 nT at
12/0114Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 112 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (13 Jun, 15
Jun) and quiet levels on day two (14 Jun).
