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
A minor geomagnetic enhancement will be possible beginning April 26th when a coronal hole stream is expected to become geoeffective. Visible aurora will be possible at very high latitudes.
