Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 63 Issued at 2200Z on 04 Mar 2013

IA.  Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 7 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be low on days
one, two, and three (05 Mar, 06 Mar, 07 Mar).

IIA.  Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 516 km/s at
04/0219Z. Total IMF reached 5 nT at 03/2116Z. The maximum southward
component of Bz reached -4 nT at 03/2323Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 6261 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (05 Mar) and quiet to unsettled levels
on days two and three (06 Mar, 07 Mar).
