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 295 Issued at 2200Z on 22 Oct 2005 IA. Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity was very low. Region 815 (S14W68) continues to decay. LASCO imagery depicts a weak, full halo CME that appears to be from a back-sided source region, first seen at 22/0942Z. No new regions were numbered today.IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 21-2100Z to 22-2100Z
The Geomagnetic field was at predominantly quiet levels, with a brief
active period observed between 22/0000Z and 22/0300Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at unsettled to active levels throughout the period.
The elevated conditions are due to a favorably positioned coronal
hole.
