Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 68 Issued at 2200Z on 09 Mar 2017

IA.  Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: 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 (10 Mar, 11 Mar, 12 Mar).

IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 582 km/s at 09/0050Z. Total IMF reached 5
nT at 09/0117Z. The maximum southward component of Bz reached -4 nT at
08/2247Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 28218 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (10 Mar,
11 Mar, 12 Mar).
