What is a Solar Outage (Attenuation)

Solar Attenuation Notification 

In early October, Late Season Solar Attenuation will take place over the Teleport.  This is predictable, and there is a small possibility that it will be service affecting for one or more of your remote sites.  This season spans roughly 5 days and lasts only a few minutes each day.

What is Solar Attenuation?

A situation in which the satellite in is a direct line between the satellite antenna and the sun.  Noise from the sun’s radiation mixes with the satellite carrier – degrading the carrier signal for a short time.
