Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 62 Issued at 2200Z on 03 Mar 2018

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 is currently 1 numbered sunspot region on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be very low
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 levels for the past 24 hours. Solar wind speed
reached a peak of 347 km/s at 02/2127Z. Total IMF reached 12 nT at
03/2036Z. The maximum southward component of Bz reached -7 nT at
03/0904Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1459 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (04 Mar) and quiet levels
on days two and three (05 Mar, 06 Mar).
