Solar interference
Twice a year, at the Spring and Fall Equinox, satellite 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 antenna. This affects any channel received via satellite and causes a signal reception outage depending on which satellite the sun is aligned with at the time. The outages usually last less than 10 minutes.
