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 206 Issued at 2200Z on 24 Jul 2008IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was very low. Region 1000 (S12W57)
remains spotless. No flare activity occurred during the past 24
hours.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was at quiet to active levels . The solar wind
speed gradually declined to around 500 km/s. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet through the forecast period ( 25 July to
27 July).
