SDF Number 67 Issued at 2200Z on 08 Mar 2017

IA.  Analysis of Solar Active Regions and Activity from 07/2100Z to
08/2100Z: 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 (09 Mar, 10 Mar, 11 Mar).

IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 610 km/s at 07/2352Z. Total IMF reached 6
nT at 08/1507Z. The maximum southward component of Bz reached -5 nT at
07/2341Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 28636 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (09 Mar) and quiet levels
on days two and three (10 Mar, 11 Mar).
