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 192 Issued at 2200Z on 11 Jul 2006

IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z

Solar activity was at very low levels. Region 899 (S06W18) underwent penumbral decay during the past 24 hours. No new regions were numbered today.
IB. Solar Activity Forecast
Solar activity is expected to remain at very low levels.
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at unsettled to minor storm levels with isolated major storm conditions possible on 12 July due to a recurrent high speed coronal hole stream. A return to quiet to unsettled levels is expected on 13 and 14 July as the coronal hole moves out of a geoeffective position.
