A strange phenomenon happened in the mountains near Kitzbuhel in Austria during sunrise on August 7, 2016.
The video uploader points out that while checking one of the Pristine webcams he noticed that at the 4:50am hour there is a light anomaly just before sunrise. Its gets daylight, turns dark again for 20 minutes then daylight once again which proceeds on the full sunrise.
He wonders whether this light anomaly is just a natural phenomenon or it is the reflection of a so-called ‘second sun’ or maybe an alien sphere.
Two reasonable explanations for this phenomenon:
The area the light is coming from is not even the horizon. The light is coming from Kitzbuhel, the town that camera is facing. Cloud cover is reflecting the light. It goes out because the sun coming up changes the background light, causing the camera to dim as it gets lighter,
Another possible explanation for this phenomenon is called ‘birefringence’ – Birefringence is responsible for the phenomenon of double refraction whereby ray of light, when incident upon a birefringent material, is split by polarization into two rays taking slightly different paths.
No aliens or a second sun, finally it seems the webcam has captured a beautiful scene of the upcoming sun over the mountains in Kitzbudel.
