Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 69 Issued at 2200Z on 10 Mar 2013

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 6 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-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 levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 363 km/s at
09/2119Z. Total IMF reached 6 nT at 09/2238Z. The maximum southward
component of Bz reached -4 nT at 10/2039Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 610 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (11 Mar, 12 Mar, 13
Mar).
