Geophysical report

Viewing archive of Wednesday, 17 March 1999

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.

Current data suggests there is a slight possibility for aurora to appear at the following high latitude regions in the near future

Edmonton, AB, Gillam, MB, Saskatoon, SK, Whitehorse, YT, Yellowknife, NT
Anchorage, AK, Fairbanks, AK, Juneau, AK, Utqiagvik, AK

The strength of the interplanetary magnetic field is moderate (17.22nT), the direction is slightly South (-0.66nT).

The Disturbance Storm Time index predicts moderate storm conditions right now (-66nT)
