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 181 Issued at 2200Z on 29 Jun 2008IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity was very low. No flares occurred during
the past 24 hours and the disk remains spotless.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 28-2100Z to 29-2100Z
The geomagnetic field was at quiet to unsettled levels. Solar wind
speed gradually decreased from approximately 530 to 470 km/s as the
effects of the coronal hole high speed stream decrease. The greater
than 2 MeV electron flux at geosynchronous orbit reached high
levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels for the next three days
(30 June - 02 July).
