Why does a black circle sometimes appear over the centre of the sun?
On occasion, a black circle or other irregular shape may appear in
front of the sun in the webcam images. Digital web cameras have image
sensors that convert light to an electronic signal. The centre of the
sun is very bright, and can overwhelm the sensor. When this happens, the
camera software blackens out the area to protect the longevity of the
sensor, and displays black pixels in the area.
What is the black or white line that sometimes appears in the photos?
A black line could be one of the guy wires of the tower on which a
camera is mounted. In certain light conditions, reflections occur on the
dome housing the camera, which can appear as a white line.
How can you tell if the white light in the sky is the moon?
If the light is relatively large and is moving across the sky, it is
the moon. Otherwise, it is a fixed object and more often than not, a
reflection from one of the station lights.
