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 066 Issued at 2200Z on 07 Mar 2010IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity was very low. Only low-level B-class
flares were observed during the period.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (08 - 10 March).
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic field was mostly quiet during the past 24 hours. A
single period of unsettled conditions was observed at mid-latitudes
between 07/0600Z and 07/0900Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be at quiet to unsettled levels on days one and two (08
- 09 March) in response to the CME observed on 06 March. Geomagnetic
field activity is expected to decrease to quiet levels on day three
(10 March) as the CME effects subside.
