CBC Radio will briefly go off-air in Calgary on Sunday and Monday due to a seasonal issue with satellites and transmitters.

Each year at this time, the sun moves behind the satellite used by CBC Radio. It causes a sort of reverse eclipse, briefly interfering with the transmitter's ability to pick up signals from the satellite.

This is temporary and will only last several minutes each day.

On Sunday, March 2, the outage will last from roughly 12:13 p.m. MT to 12: 20 p.m. MT.

On Monday, March 3, the outage will last from roughly 12:14 p.m. MT to 12:19 p.m. MT.

I deal with sun transit seasonally every year with VSAT systems. This is why satellite is typically my last technology of choice which I spec when there are no other economical or technical options available.
If the location has enough link budget though, it may have enough signal to noise to continue operation.
