SYNOPSIS OF TODAYS ACTIVITY
---------------------------
Solar activity was high. Region 1045 (N23W01) produced
two M-class events during the past 24 hours. The first was a M1 at
06/2137Z and the second was a M6/1n at 07/0224Z. The soho/lasco C2
imagery observed a cme off the east limb with the first event and a
full halo with the second event. The M6 x-ray event had an
associated eit wave, and a tenflare of 170sfu. This region has
retained a magnetic beta-gamma configuration with a possible delta
magnetic configuration within its interior spots. A new region was
numbered today as region 1046 (N25E65).
Solar activity forecast: solar activity is expected to be low
to moderate with M-class events likely. There is a slight chance
for a X-class event from region 1045.
The geomagnetic field was quiet.
Geophysical activity forecast: the geomagnetic field is
expected to be unsettled with isolated active conditions for the
next three days (08-10 february) due to a recurrent coronal hole
high speed stream and cme effects.
