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 069 Issued at 2200Z on 10 Mar 2010IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity was very low. Two B-class flares
occurred during the past 24 hours. The first was estimated to be a
B3 at 0713Z from spotless plage (in the location of old Region 1046.
The x-ray flux maximum was estimated because it occurred during
GOES-14 eclipse). This event was associated with a CME from the East
limb. The second event was a B1.7 at 1534 UTC that originated from
newly emerged Region 1054 (N12E56), which is currently a small BXO
beta sunspot group. There also appeared to be emerging flux and
possible spot formation near S23W00 but observations are too
preliminary to warrant a Region number assignment.
IB. Solar Activity Forecast
Solar activity is expected to be very
low for the next three days (11-13 March). However, there is a
slight chance for an isolated C-class event from the newly emerging
regions if they continue to grow.
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic field was quiet to unsettled during the past 24
hours.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet for the next three days (11-13 March).
