Geomagnetic Activity and Aurora Forecast

NOTICE:
The forecast data below is provided by the NOAA Space Weather Prediction Center (SWPC) and is based on the latest available data and modelling. When it comes to spaceweather, current geomagnetic conditions can change rapidly and without notice. Be sure to monitor the SolarHam website for the most up to date information.

Geomagnetic and Aurora Forecast
Geomagnetic activity is expected to be at fairly quiet levels during the next few days. Widespread aurora beyond the Arctic Circle is now currently expected.
