Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 060 Issued at 2200Z on 29 Feb 2008
IA. Analysis of Solar Active Regions and Activity from 28/2100Z
to 29/2100Z: Solar activity was very low. A weak CME was observed
at 29/0025Z from STEREO and LASCO imagery in the vicinity of Region
983, which is approaching the west limb at S06. This activity does
not appear to be Earth directed.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was at unsettled to minor storm conditions.
Solar wind speed remained elevated due to the continued influence of
a recurrent coronal hole high speed stream. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at predominately unsettled levels, with isolated
active periods for 01-02 March. Conditions are expected to decrease
to quiet to unsettled levels on 03 March as the high speed stream
rotates out of a geoeffective position.
