Solar outage time again, where the sun can disrupt satellite signals — 2 Comments


    The bi-annual loss of satellite signal is at its maximum today in northern Europe. At around 10.40 am local time, BBC and ITV transmissions will disappear for up to 14 minutes as the satellites pass in front of the sun. Radiation blots out the UK-only beams during the transit. Stronger Europe beams such as those used by Sky’s entertainment services are also affected, but normally stay above the reception threshold.
    Sun outage has been affecting southern Europe for the past week but will ease shortly. As the loss is in the mornings, only couch potatoes or radio listeners normally notice.
    The satellites are in a sun-earth-satellite straight line, as it’s the equinox for the Clarke Belt. At night, they pass through the earth’s shadow for a number of hours, requiring battery power to operate. (The sun’s light provides power at other times)
    Odd effects will be noticed during transition into the complete darkness of the earth’s shadow. Some areas experience better reception than normal around late evening and midnight but lose the signal completely during the switch to batteries.
    The closer you are to the UK, the less the effect.
    It’s also a good time to check for obstructions to your dish. Any shadows falling on the face indicate shading from an object or foliage.

    • This happens in October, not December.
      So the date of “21-12-2016” you have been given is totally wrong.
      The issue happens at the equinoxes.
