SYNOPSIS OF TODAYS ACTIVITY
---------------------------
Solar activity was moderate. Region 1410 (N17W67)
produced an M1 x-ray flare at 06/2000Z.
Solar activity forecast: solar activity is likely to be low
with a chance for moderate levels from region 1410 for days 1 and 2
(7-8 february). Very low to low level are expected on day 3 (9
february) after region 1410 transits off the west limb of the solar
disk.
The geomagnetic field was mostly quiet.
Geophysical activity forecast: the geomagnetic field is
expected to be mostly quiet for days 1-2 (7-8 february). Activity
should increase to unsettled and active levels late on day 3 (9
february) from the onset of coronal hole high speed stream effects.
