Activiteitenrapport
Bij elke genoemde zonnevlam in dit rapport werd een schaalfactor toegepast door het Space Weather Prediction Center (SWPC). Vanwege de SWPC-schaalfactor worden zonnevlammen 42% kleiner gerapporteerd dan voor de wetenschappelijke data. De schaalfactor werd verwijderd uit onze gearchiveerde zonnevlamdata om de werkelijke fysieke eenheden weer te geven.
Rapport van de zonne- en geofysische activiteit van 2001 Nov 01 2200 UTC

IA. Analyse van de actieve zonneregio's en zonneactiviteit van 31-2100Z tot 01-2100Z
Solar activity has been high due to five M-class events
observed during the past 24 hours. The largest of these was an M3/Sf
at 1210 UTC from newly numbered Region 9687 (S19E71). Region 9687
produced three additional M-class events and exhibited frequent
brightenings throughout the day. An additional M-class event (M1/Sf)
came from Region 9678 (N07W75) at 0653 UTC. Region 9682 (N11W22)
continues to dominate the disk in terms of apparent size and
magnetic complexity, and also exhibited occasional flare activity
during the day, some of which were occurring at the same time as
flare activity in Region 9687. SXI imagery clearly indicated,
however, that new Region 9687 was the dominant contributor to the
X-ray flux during the four M-class events mentioned previously.
IB. Voorspelling zonneactiviteit
Solar activity is expected to be
moderate to high. M-class events should continue, with regions 9687
and 9682 being the main contributors to activity. There continues to
be a chance for an isolated major flare event or proton producing
event during the next three days.
IIA. Samenvatting geofysische activiteit 31-2100Z tot 01-2100Z
The geomagnetic field ranged from unsettled to minor storm levels
during the past 24 hours. Approximately five hours after yesterday's
shock at 31/1352 UTC, the interplanetary magnetic field turned
southward and maintained moderately strong negative values (-8 to
-12 nT) from 31/1810 UTC until around 01/1710 UTC. This led to
mostly active levels, with a minor storm period from 0600-0900 UTC.
At forecast issue time activity had declined to unsettled and Bz was
weakly northwards.
IIB. Voorspelling geofysische activiteit
The geomagnetic field is
expected to be mostly unsettled for the next three days.
