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 211 Issued at 2200Z on 30 Jul 2006IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity continued at very low levels again
today. New Region 902 (S10W21) was numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels.
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to range from unsettled to active conditions with minor
storm periods possible. This activity is due to a coronal hole high
speed stream moving into a geoeffective position during the forecast
period (31 Jul to 02 Aug).
