Solaktivitetsrapport
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 331 publicerat klockan 2200Z på 27 Nov 2001IA. Analys av solfläcksgrupper och solaktivitet från 26-2100Z till 27-2100Z Solar activity was at low levels. There were numerous
C-class flares observed during the period. The vast majority of
these flares appeared to originate from source regions beyond the
east limb (based on SXI imagery). Region 9715 (N05E30) produced
a single optically correlated C6/Sf flare at 27/1552 UTC.
This region has continued to show growth in magnetic complexity and
areal coverage. Region 9715 remains the most noteworthy region on the
visible disk. New Region 9717 (N06E78) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
predominantly low to moderate levels. Region 9715 has the potential
to produce isolated M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 26-2100Z till 27-2100Z
The geomagnetic field has been at quiet levels. The greater than 10
MeV proton event (began 22/2320 UTC, max 18900 pfu at 24/0555 UTC)
remains in progress although flux values have been oscillating
across event threshold levels throughout the past ten hours of the
period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels. Isolated active
conditions are possible during the forecast period due to a southern
hemisphere coronal hole.
