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 075 Issued at 2200Z on 16 Mar 2006IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z Solar activity continues at very low levels. There are
just a couple of small, insignificant sunspot groups on the visible
disk.
IB. Solar Activity Forecast
Solar activity continues at very low
levels.
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled on 17 and 18 March. A high speed
coronal hole stream is expected to become geoeffective on 19 March,
and produce isolated active to minor storm conditions.
