A sun outage is an interruption in satellite signals caused by interference from solar radiation. Satellites transmitting cable networks can be affected by solar interference as they align with the sun. Sun outages may cause the video on a few channels to break up into blocks for a period of a several minutes. Afterward, the picture usually goes back to normal on its own.
This phenomenon can happen twice a year—before the March equinox (February and March) and after the September equinox (September and October). Sun outages only affect cable service, internet and phone services are not affected.
