Geophysical report

Viewing archive of Wednesday, 16 November 2005

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.

G2 - Moderate geomagnetic storm

Observed Kp: 6
Threshold reached: 22:29 UTC

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

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

Tórshavn
Oulu, Kuopio
Trondheim
Luleå, Sundsvall, Umeå

The solar wind speed is currently moderately high (595.4 km/sec.)

The strength of the interplanetary magnetic field is high (21.5nT), the direction is North (9.03nT).

The Disturbance Storm Time index predicts moderate storm conditions right now (-60nT)
