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 076 Issued at 2200Z on 16 Mar 2008IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z Solar activity was very low. Region 986 (S04W57) is
currently an Hsx Alpha magnetic class with only one spot.
IB. Solar Activity Forecast
Solar activity is expected to remain
very low.
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit remained at high levels.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be mostly quiet with isolated unsettled periods for the
next three days (17-19 March).
