Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 62 Issued at 2200Z on 03 Mar 2017

IA.  Analysis of Solar Active Regions and Activity from 02/2100Z to
03/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 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 (04
Mar, 05 Mar, 06 Mar).

IIA.  Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 762 km/s at 03/1122Z. Total IMF
reached 6 nT at 03/1843Z. The maximum southward component of Bz reached
-5 nT at 03/0726Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 22830 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to active levels on day one (04 Mar), quiet to
unsettled levels on day two (05 Mar) and quiet levels on day three (06
Mar).
