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 176 Issued at 2200Z on 25 Jun 2007IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z Solar activity was very low. New region 961 (S09E77)
is currently classified as an Hsx alpha sunspot group. No
significant flares have occurred in the past 24 hours.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain quiet from 26 to 28 June.
