Report of Solar Geophysical Activity (RSGA)

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 69 Issued at 2200Z on 10 Mar 2014

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was an M1 event observed at
10/1528Z from Region 2002 (S19E37). There are currently 6 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(11 Mar, 12 Mar, 13 Mar).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
350 km/s at 10/1330Z. Total IMF reached 6 nT at 10/0956Z. The maximum
southward component of Bz reached -4 nT at 10/0911Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 103 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (11 Mar) and quiet levels
on days two and three (12 Mar, 13 Mar).
