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 060 Issued at 2200Z on 01 Mar 2003

IA. Analysis of Solar Active Regions and Activity from 28-2100Z to 01-2100Z

Solar activity was at low levels. There were several C-class flares today: one C5.1 at 0115 UTC from Region 297 (S16E67), a C2.4 at 0842 UTC and a C3.0 at 1432 UTC from Region 292 (S07 on the West limb), and 4 separate C-Class flares from Region 296 (N13E78). Region 297 (S16E67) was newly assigned today. SXI images from GOES-12 show yet another new region behind the East limb at approximately S20.
IB. Solar Activity Forecast
Solar activity is expected to be at low levels for the next three days.
IIA. Geophysical Activity Summary 28-2100Z to 01-2100Z
The geomagnetic field was at unsettled to active levels due to a high speed coronal hole stream which has nearly passed. At geosynchronous orbit, the greater than 2 MeV Electron fluxes reached high levels today.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels for the next two days, increasing to unsettled to active levels on day three.
