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 286 Issued at 2200Z on 13 Oct 2009IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity was very low. No flares were observed.
The visible disk remained spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet levels on day 1 (14 October). Activity is
expected to increase to quiet to unsettled levels on days 2 - 3 (15
- 16 October) as an equatorward extension of the northern crown
coronal hole begins to influence the field.
