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 205 Issued at 2200Z on 24 Jul 2006IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was low. A C1 flare occurred at 24/1501
UTC from a region on the east limb at approximately S12. No new
regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to be very
low to low.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was mostly quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with possible active conditions on
25 July due to coronal hole activity. On 26 and 27 July, quiet to
unsettled conditions are expected.
