USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 301 gepubliceerd omstreeks 2200Z op 28 Oct 2002IA. Analyse van de actieve zonneregio's en zonneactiviteit van 27-2100Z tot 28-2100Z
Solar activity has been moderate due to an M1/1n flare
at 1205 UTC from Region 162 (N25W59). Region 162 continues to show
flux emergence and consolidation in the western portion of the
trailer spots where the group has a delta configuration. Additional
frequent C-class subflares were produced by this region throughout
the day. New Region 173 (S17W69) emerged on the disk today and new
Region 172 (S17E44) was assigned. An erupting prominence was
observed near the northeast limb beginning around 2200 UTC and was
associated with a narrow CME in LASCO as well as a type II sweep
with shock velocity of 1015 km/s. The event was promptly followed by
a back-sided full halo CME which was first observed in LASCO at 2326
UTC.
IB. Voorspelling zonneactiviteit
Solar activity is expected to be
moderate because of Region 162. There continues to be a slight
chance for major flare activity from this region as well. The
current observations of strong activity behind the east limb suggest
that there is likely to be a gradual increase in background levels
and activity levels over the next three days.
IIA. Samenvatting geofysische activiteit 27-2100Z tot 28-2100Z
The geomagnetic field was unsettled to active. Solar wind signatures
continue to indicate the presence of a high speed solar wind stream
associated with a coronal hole. The greater than 2 MeV electron
fluxes reached high levels today.
IIB. Voorspelling geofysische activiteit
The geomagnetic field is
expected to be mostly unsettled for the next three days as the
currently enhanced conditions are expected to subside.
