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 065 Issued at 2200Z on 06 Mar 2007IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 05-2100Z to 06-2100Z
The geomagnetic field was mostly quiet to active. A single period of
minor storming was observed at all latitudes from 06/0300 - 0600Z.
Solar wind speed has been increasing to approximately 580 km/s
throughout the day, indicating the arrival of a coronal hole high
speed stream.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled with isolated active periods on 07
March due to the recurrent coronal hole. Expect quiet conditions on
08 - 09 March as the coronal hole rotates out of its geoeffective
position.
