Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 73 Issued at 2200Z on 14 Mar 2017

IA.  Analysis of Solar Active Regions and Activity from 13/2100Z to
14/2100Z: 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 (15 Mar, 16 Mar, 17 Mar).

IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 387 km/s at 14/0428Z. Total IMF reached 5 nT at
14/1234Z. The maximum southward component of Bz reached -5 nT at
14/1236Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 8795 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (15 Mar, 16 Mar) and quiet to
unsettled levels on day three (17 Mar).
