SYNOPSIS OF TODAYS ACTIVITY
---------------------------
Solar activity was at very low levels. The disk and
limb was quiet and stable with no earth-directed cmes observed
during the period.
Solar activity forecast: solar activity is expected to be very
low to low for the next three days (04 - 06 february).
The geomagnetic field was at quiet to unsettled levels with isolated
high latitude active periods due to the waning effects of a
geoeffective coronal hole high speed stream. During the period, ace
satellite observations indicated wind speeds averaged about 425 km/s
while the bz component of the interplanetary magnetic field varied
between +/- 5 nt.
Geophysical activity forecast: the geomagnetic field is
expected to be at mostly quiet levels for the next three days (04 -
06 february).
