A sun outage is an increase of noise floor to the receive antenna which will cause higher bit errors or total loss of service. At these times the pointing angles from your antenna or the teleport antenna to the satellite and to the sun are equal or close to each other. The satellite is in line of sight to the sun. The solar radiated energy from the sun can also cause damage to the LNB because of electromagnetic energy and heat.
NYNEX is pleased to release an integrated calculator which provides exact date and time of service outages caused by sun interference for teleports as well as for all connected remote sites.
