Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 63 Issued at 2200Z on 04 Mar 2018

IA.  Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: 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 (05 Mar, 06 Mar, 07 Mar).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 461 km/s at 04/0522Z. Total IMF reached 13
nT at 04/0121Z. The maximum southward component of Bz reached -11 nT at
04/0121Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1286 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (05 Mar, 06 Mar, 07
Mar).
