SYNOPSIS OF ACTIVITY
--------------------
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.
Solar activity forecast: solar activity is expected to be very
low.
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.
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.
