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

Reykjavik

The solar wind speed is currently moderately high (572.2 km/sec.)

The strength of the interplanetary magnetic field is high (23.8nT), the direction is North (14.13nT).

The Disturbance Storm Time index predicts moderate storm conditions right now (-62nT)
