Not sure if it is the right forum, but anyways,

In this image, the sun is to the left. What causes the glow at the middle?

I believe it is a sun dog - see these pictures.

Note the picture at Stonehenge is very like what you saw. The sun the the small blob.

A sun dog brighter than the sun itself?

I think it far more likely that behind that ridge you will find a brightly lit shopping mall, athletic field, airfield, or some similar source of light.

Excellent point. I believe you've nailed it. I was misled by the OP"s assertion that the Sun was the light on the left.

I'm not convinced it is a sun dog. do a google image search and none look like this. I don't have another explanation though. You would think the centre light to be the Sun though.

unfortunately the OP'er hasnt returned

What I would like to know is ...

1) Did he/she take the photo or was it found somewhere ?
2) If they actually took the photo, was it visible to the eye or was it only seen in the photo?
that would determine if it was an artifact created in-camera ?

it does look too sharp and defined for a sundog !

ohh my other thought following from my previous post

Question 3...

if the OP'er took the pic, was it taken through a window ?
if so, there may have been a window on another building out of camera shot, that was reflecting and projecting the sun image onto the window through which the photo was taken ?



maybe not valid ... just thinking outside of the box

cheers

Thanks for the replies so far.

I'm pretty sure the light on the left is the sun. It's been very cloudy these days so I can't get a picture.

Perhaps the glow is simply a break in the clouds?

what were the time and date?

what were the latitude and longitude?

what were the angles of the two objects from south? (and in particular, is the angle between them 22 degrees?)
