Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 69 Issued at 2200Z on 10 Mar 2017

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: 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 (11 Mar, 12 Mar, 13 Mar).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 512 km/s at 09/2348Z. Total IMF reached 6
nT at 10/0740Z. The maximum southward component of Bz reached -5 nT at
10/0743Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 12580 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (11 Mar,
12 Mar, 13 Mar).
