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)
