Image Details:

Green and Red Rim.

The image captures a green segment on the top-left limb of the sun. Green rim is an optical phenomenon visible due to the refraction of sunlight through increasing density near horizon. The refraction of green light is stronger and thus a "green" sun can be visible higher than the "red" sun creating a green rim on the upper limb. On the other hand, the lower limb becomes reddish, which is known as the Red rim.

They do not last long and are not visible to unaided eyes. They are pretty faint and become most prominent when the sun is between 1° to 2° above the horizon.

A total of 4 images were captured with an interval of 3 seconds each.
