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 064 Issued at 2200Z on 05 Mar 2010IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity was very low. Todays flare activity
consisted of just a few, low-level B-class events. Regions 1052
(S16W82) and 1053 (S22W89) appeared to be quieter today as they
approached the west limb. A small, slow CME was observed on the west
limb at about 05/0054Z and was associated with a weak wave in
STEREO-A EUVI imagery. The wave appeared to originate near Region
1051 (N16W53).
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (06-08 March).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next three days (06-08 March).
