Geophysical report

Viewing archive of Friday, 26 March 2010

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 slight possibility for aurora to appear at the following high latitude regions in the near future

Tórshavn
Reykjavik
Trondheim

The solar wind speed is currently moderately high (589.7 km/sec.)

The strength of the interplanetary magnetic field is high (23.86nT), the direction is North (13.66nT).

The Disturbance Storm Time index predicts moderate storm conditions right now (-59nT)
