Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Weather Prediction Center and the U.S. Air Force.

Updated Mar 01 2200 UTC

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 061 Issued at 2200Z on 01 Mar 2012

IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 01/2100Z:  Solar activity has been low. There was one C-class
flare duing the past 24 hours, a C3/1f from Region 1423 (N17W21) at
01/1526Z. New Region 1427 (N15W01) was numbered today. A CME was
observed at 29/1824Z (using LASCO C2) from the north polar region of
the sun, however it is not expected to be geoeffective.

IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low.

IIA.  Geophysical Activity Summary 29/2100Z to 01/2100Z:
The geomagnetic field has been quiet to active with isolated storm
periods at high latitudes. The elevated activity appears to be
related to a solar sector boundary crossing.

IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the first and second days
(02-03 Mar) due to a small yet well positioned coronal hole.  A
return to quiet levels is expected on the third day (04 Mar).
