Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 67 Issued at 2200Z on 08 Mar 2019

IA.  Analysis of Solar Active Regions and Activity from 07/2100Z to
08/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
08/0319Z from Region 2734 (N08W17). There are currently 1 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a slight chance for a C-class flare 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 445 km/s at 07/2103Z. Total IMF reached 8
nT at 07/2111Z. The maximum southward component of Bz reached -7 nT at
07/2108Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 2983 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (09 Mar, 10 Mar)
and quiet to minor storm levels on day three (11 Mar).
