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 312 publicerat klockan 2200Z på 08 Nov 2003IA. Analys av solfläcksgrupper och solaktivitet från 07-2100Z till 08-2100Z Solar activity was very low. Two new regions emerged
today: Region 498 (S03W26) and Region 499 (S17W19). Both of these
regions are small and simple. A 20 degree filament running from
S10W01 to S20W20 faded between 07/2200 UTC and 08/0200 UTC.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low.
IIA. Sammanfattning av geofysisk aktivitet 07-2100Z till 08-2100Z
The geomagnetic field ranged from quiet to unsettled levels during
the past 24 hours. A noticeable increase was seen in solar wind
magnetic field and density, beginning around 1000-1200 UTC which
transitioned activity from quiet levels to unsettled levels. The
signatures appear to be consistent with a co-rotating interaction
region which presages the onset of an expected high-speed coronal
hole solar wind stream. The greater than 10 MeV proton fluxes were
enhanced but below threshold today, and showed a steady downward
trend during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled to active for 09-10 November as the
coronal-hole driven disturbance is expected to commence. Mostly
active conditions are expected to prevail on 11 November.
