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 210 Issued at 2200Z on 29 Jul 2006IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 29-2100Z Solar activity was very low.
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 mostly quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet on 30 July. On 31 July through 01
August, a coronal hole high speed stream is expected to move into
geoeffective position causing unsettled to active conditions with
minor storm periods possible.
