Having SatCom problems?

A burst of radiation on the sun's surface may trigger a geomagnetic storm, which can disrupt satellite communications.
In order to prevent unnecessary maintenance on satellite communications systems Air Sat One has provided a feed of Geophysical Events from NOAA's Space Weather Prediction Center. Check here to see if solar activity could be a cause of satellite communications problems.
