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 2005IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity has been very low. Region 815 (N08E60)
grew slightly and was the only active region on the visible disk.
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 quiet. A solar sector boundary crossing
was observed at ACE at 15/0000 UTC. The greater than 2 MeV electron
flux at geosynchronous orbit remained at high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet. Unsettled and isolated active conditions are
possible on 16 October from the influence of a geoeffective coronal
hole solar wind stream.
