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 316 publicerat klockan 2200Z på 11 Nov 2000IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z Solar activity was low. There were two C-class flares
produced during the past 24 hours. The first was a C2/Sf at 0012Z
from Region 9218 (N21W90+), and the second was a C2 which was not
reported optically. An examination of SOHO/EIT images during the
second event strongly suggest that it also originated from Region
9218. Region 9221 (S12W20) showed some magnetic flux development in
the leader part of the group and Region 9227 (S12E12) displayed new
spot growth just behind the leader spot. All regions currently on
the disk are quiet and stable.
IB. Prognos för solaktivitet
Solar activity is expected to be
predominantly low for the next three days, but there is a slight
chance for an isolated M-class event.
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
The geomagnetic field has been quiet to unsettled during the past 24
hours. Solar wind measurements from ACE indicate the onset of a
high-speed, low density flow that is consistent with a favorably
positioned solar coronal hole. The interplanetary magnetic field,
however, has been either northwards or has been fluctuating weakly
between -3 nT and +5 nT, and the geomagnetic response so far has
been weak. The proton event at greater than 100 MeV ended at 0240Z
today (based on GOES-8 flux dropping below 1 pfu). The greater than
10 MeV protons decreased during the past 24 hours but continue to be
above the event threshold of 10 pfu, with a current value at 2100Z
of 23.6 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled to active during the next 24 hours due to
possible enhanced activity from the high speed solar wind stream. A
decline to mostly unsettled is expected for the second and third
days. The greater than 10 MeV proton event is expected to end
sometime during the next 24 hours.
