Sun Transit Summer Season August 8 – August 11

Please be advised that we are approaching the Summer Sun Transit season for 2018, which will occur between the dates of August 8 – August 11, 2018.


Sun transits occur when the sun crosses the earth’s equatorial plane during the spring and fall equinoxes. At these times, the sun aligns directly behind the satellites for a few minutes each day. When the sun moves directly behind the satellite 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 every day during this occurrence.

Sun Transit


The time of occurrence depends both on the geographic location of the earth station and the location of the satellite. The sun may degrade the signal for several minutes depending on the antenna size and available link margin, although it is not unusual for the effect to go unnoticed.
