Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 70 Issued at 2200Z on 11 Mar 2014

IA.  Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was an M3/1f flare observed
at 11/0350Z from Region 1996 (N14W64). There are currently 5 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be moderate
with a slight chance for an X-class flare on days one, two, and three
(12 Mar, 13 Mar, 14 Mar).

IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z: 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 360 km/s at
11/0913Z. Total IMF reached 6 nT at 11/1150Z. The maximum southward
component of Bz reached -3 nT at 11/1434Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (12 Mar, 13 Mar, 14
Mar).
