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 64 Issued at 2200Z on 05 Mar 2013IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
05/0754Z from Region 1686 (S14W59). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares on days one and two (06 Mar, 07 Mar) and
expected to be very low with a chance for a C-class flares and a slight
chance for an M-class flare on day three (08 Mar).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
437 km/s at 05/0131Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 7332 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (06 Mar, 07 Mar)
and quiet levels on day three (08 Mar).
