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.

- Potential Impacts: Area of impact primarily poleward of 55 degrees Geomagnetic Latitude.
- Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms.
- Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible.
- Radio - HF (high frequency) radio propagation can fade at higher latitudes.
- Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state.
