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 165 Issued at 2200Z on 13 Jun 2008IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity was at very low levels. Region 998
(S10E12) decayed slightly in area from 30 millionths to 20
millionths during the summary period.
IB. Solar Activity Forecast
Solar activity is expected to remain
at very low levels.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was at quiet levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to remain at quiet levels for days one and two (14 and 15
June) of the forecast period. Conditions are expected to increase
to quiet to unsettled levels with a slight chance of isolated active
periods on day three (16 June) due to a coronal hole high speed
stream rotating into a geoeffective position.
