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 063 Issued at 2200Z on 04 Mar 2010

IA. Analysis of Solar Active Regions and Activity from 03-2100Z to 04-2100Z

Solar activity was low. Todays activity consisted of a C2 x-ray event at 1611Z from Region 1052 (S17W70), as well as numerous B-class events. Regions 1052 and 1053 (S22W77) showed slow growth during the past 24 hours and exhibited slightly elevated levels of activity. An overall increasing trend was noted in the x-ray background levels.
IB. Solar Activity Forecast
Solar activity is expected to be very low to low. There is a chance for isolated C-class events during the next three days (05-07 March).
IIA. Geophysical Activity Summary 03-2100Z to 04-2100Z
The geomagnetic field was mostly quiet during the past 24 hours. Solar wind observations from the ACE spacecraft showed a small increase in speed with values ranging between 440-460 km/s at the end of the reporting period.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be predominantly quiet for the next three days (05-07 March).
