Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 173 Issued at 2200Z on 22 Jun 2018

IA.  Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (23 Jun,
24 Jun, 25 Jun).

IIA.  Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 408 km/s at 21/2218Z. Total IMF reached 6 nT at
22/2042Z. The maximum southward component of Bz reached -3 nT at
22/1426Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 263 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (23 Jun) and quiet to unsettled levels
on days two and three (24 Jun, 25 Jun).
