Internet in the Arctic...from Qiniq today
Sun transits occur when the sun crosses the earth's equatorial plane during the spring and fall equinoxes (late February or early March; September or October). At these times, the sun aligns directly behind the satellites for a few minutes each day. When the sun moves directly behind the satellite to your receive antenna, the satellite signal can be overwhelmed by the enormous amount of thermally generated radio frequency (RF) noise radiated by the sun. This can cause reception interference for a few minutes everyday during this occurrence. At the peak there will be 3 interruptions a day as the sun passes your local community, our Ottawa uplink facility and our Yellowknife facility.
