안녕하세요.

태양과 위성, 지구가 일직선을 이뤄 위성신호 수신에 장애가 발생하는 태양간섭 장애 기간입니다.

이 장애는 매년 봄, 가을에 발생하며, 위성안테나의 크기나 위성의 거리에 따라 짧게는 2~3일, 길게는 보름 정도, 매일 10분에서 30분동안 장애가 발생합니다.

45Cm 안테나를 사용하는 무궁화3호의 신호를 수신하는 경우(스카이라이프 포함), 대략 10일 동안 5분에서 10분 정도 영향을 받을 것이며, 거리가 먼 C-band 위성신호인 경우, 15분에서 많게는 30분 동안 장애가 발생할 수 있습니다.

장애초기에는 방송화면에 흰 줄이 생기기 시작하여, 색종이 같은 모자이크 증상, 심하면, 방송 자체가 끊기는 현상이 발생하며, 장애시간을 벗어나게 되면, 다시 정상적인 시청이 가능합니다.

혹시, 장애 시간을 벗어났음에도 정상적인 방송 시청이 불가능한 경우는, 수신기를 껏다가 켜보시기 바랍니다.

Each Spring and Fall, cable companies experience a technical phenomenon called "sun outages." For a period of about 2 weeks, the sun causes "solar interference" to all geostationary satellite signals. As the sun's path across the sky gets lower each day, there are times when it is in a direct line behind a communication satellite that is sending signals to a receiving satellite dish here on earth. When the dish antenna is looking into the sun, the interference from the sun overrides the signals from the satellite. This is when a sun outage occurs.

Sun outages typically occur during the months of February/March and September/October and can last as long as 15 minutes a day and take place over a period of 15 days. The effects of a sun outage vary in degree from minimal to total outage throughout the 15 day period. Once it reaches its peak, the interference will gradually decrease becoming less noticeable each day after.

Unfortunately, there is technically nothing we can do to prevent sun outages from occurring. Each satellite service that we receive signals from will experience this interference at predictable times. During these times, we will provide a schedule for you to confirm the possibility that the channel you may be viewing is experiencing a sun outage. We apologize for any inconvenience this may cause you.

Sun Outage Effects At first, the effects of a sun outage are minimal, beginning as "sparkles" in the picture during the first days. Gradually, it worsens to the point of total outage. Some channels will experience "blocks" or "freeze frames" in the picture before and after the peak times. These are the channels we receive digitally from the satellite.
Interference begins as "sparkles" gradually becoming more "snowy".	Some channels will get "blocks" or "freeze frames" in the picture.
Once it reaches its peak, the interference will gradually decrease becoming less noticeable each day after. Unfortunately, there is technically nothing we can do to prevent these sun outage effects. The best advice we can offer when experiencing this phenomenon is to be patient while the sun outage passes naturally.
