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 288 Issued at 2200Z on 15 Oct 2003IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity has been very low. A new region was
numbered today as Region 480 (N20W26).
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field was at unsettled to minor storm conditions with
isolated major storm conditions at high latitudes. These effects
are the result of a coronal hole high speed stream. The greater
than 2 MeV electron flux reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at unsettled to minor storm conditions for 16-17
October. Unsettled to active levels are expected for 18 October.
