  [VIDEO: three progressively brighter "suns," left to right in a closely spaced row]
The ghost images in the video resemble the Sun and are separated by only 2 or 3 degrees (4-6 Sun widths), so we can rule out atmospheric phenomena.
Sun dogs or parhelia have shapes different from the Sun and appear 22 degrees away from it.

The effect is more likely due to looking through a double-paned window at an oblique angle.
The bright image on the right is the Sun viewed directly.
The image in the middle is a reflection by the inner glass surfaces facing each other, offset due to the gap width and the viewing angle.
The faint image on the left is a further reflection of the middle image.
