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 290 Issued at 2200Z on 16 Oct 2008IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z Solar activity was very low with no flares observed.
Region 1005 (N26W29) was quiet and stable during the period. Region
1006 (S27W63) was numbered today and is an alpha magnetic
configuration. This region exhibits New Cycle 24 magnetic polarity.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic field was mostly quiet. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet all three days of the forecast period
(17 - 19 October).
