Solar activity report
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.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 312 Issued at 2200Z on 08 Nov 2003IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 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. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 07-2100Z to 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. Geophysical Activity Forecast
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.
