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.

IA. Analyse van de actieve zonneregio's en zonneactiviteit van 18-2100Z tot 19-2100Z
Solar activity was at high levels. Region 9661
(N16W35) was very active producing two X class flares. The first
flare was a X1/2b at 19/0105 UTC with an associated Type II radio
sweep (914 km/s). The second flare was a X1/2b at 19/1630 UTC with
an associated Type II radio sweep (738 km/s). SOHO/LASCO imagery
shows full halo CMEs associated with both events. A Type IV radio
sweep was also detected with both CME events. Other activity was
centered around Region 9658 (S14W61). This region produced an M5/1b
flare at 19/0943 UTC and several other minor M-class and C-class
flares. New Region 9674 (S08E34) was numbered today.
IB. Voorspelling zonneactiviteit
Solar activity is expected to be at
moderate to high levels. Region 9658 and Region 9661 are very
active producing major flares. There has been very little change in
their characteristics from yesterday, so the potential for a major
flare remains good.
IIA. Samenvatting geofysische activiteit 18-2100Z tot 19-2100Z
Geomagnetic activity was quiet to unsettled. Greater than 10 MeV
proton levels was enhanced due to the two CMEs from Region 9661, but
remained just below event threshold.
IIB. Voorspelling geofysische activiteit
Geomagnetic activity is
expected to be at quiet to unsettled conditions for day one. Quiet
to minor storm levels are expected on day two and three with the
possibility for isolated major storm conditions. Analysis of the
full halo CME (19/0105 UTC from Region 9661) indicated shock arrival
late on day two or early on day three (57-72 hour transit time).
The shock arrival from the second full halo CME (19/1630 UTC from
Region 9661) is expected to arrive late on day three of the period
(76-81 hour transit time). Greater than 10 MeV proton levels may
exceed event threshold on the first day of the period. Further
enhancements may occur if major flare activity continues.
