SDF Number 178 Issued at 2200Z on 26 Jun 2020

IA.  Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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 (27 Jun, 28 Jun, 29 Jun).

IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 470 km/s at 26/0320Z. Total IMF reached 8 nT at
26/2058Z. The maximum southward component of Bz reached -7 nT at
26/2016Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 144 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (27 Jun,
28 Jun, 29 Jun).
