Sun Outages

Twice a year, at the Spring and Fall Equinox, satellite downlink sites in the Northern Hemisphere experience reception interruptions due to the transition of the sun. Reception interruptions span a period of about ten days as the sun aligns directly above the satellite and the downlink antenna. Interference gradually increases through the transit time period, peaks, and then subsides as the transit period ends. The start and end dates of the sun outage cycle for your geographical location determines the severity of the interference on any given day. Sun outages are predictable, so you can be prepared.
