There is an article about this every autumn and spring and the newspapers always seem to make a big deal about it.

The worst part is that evey year when they do an article about it, they talk about the summer and winter equinoctes. Since they occur midway between summer and winter I'm always at a loss to know which is which!

Its got nothing to do with the equinox, its got to do with the time of the year that the sun passes behind the equitorial orbit location of the satellite of concern, which is OptusD1 160E in our situation, so naturally it varies for each satellite.

So to further explain, at somepoint in the annual oribt of the sun it (the sun that is) appears from the same location as the satellite (or more exactly directly behind it) the energy from the sun overpowers the signal from the satellite (by many thousands of times) which swamps your reception.

Also for services that are being fed through from other satellites into Skys network, sun outage occurs for them also (ie swamping the reciever at Mt Wellington or Albany) which will be at a totally different time or month even to 160E depending on what satellite those services are being recived from.

Summer and Winter have Solstices (Sun furthest from the Equator).
Spring and Autumn have Equinoxes (Sun crosses the Equator).
Twice a year the Sun passes directly behind the Satellites (or more correctly the satellites orbits pass in front of the Sun) which are in stationary orbit above the equator.
