September marks the beginning of the Autumnal Equinox. Customers will begin to notice satellite signal outages increase in duration up to September 23rd, after which they will decrease. Satellites in the Eastern Sky will experience outages in the late morning and satellites in the Western Sky will experience outages during the afternoon. A reminder that customers may need to reboot their satellite receivers after the solar outage has passed to restore service.
The September equinox occurs the moment the Sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from north to south. This happens either on September 22, 23, or 24 every year.
The Earth’s axis is tilted at an angle of approximately 23.5° in relation to the ecliptic, the imaginary plane created by the Earth’s path around the Sun. However, the tilt’s orientation changes throughout the year. On any other day of the year, the Earth’s axis tilts a little away from or towards the Sun. But on the two equinoxes, the Earth’s axis tilts neither away from nor towards the Sun and is perpendicular to the Sun’s rays, as shown in the image below.
