But surely at 0800 the sun is above the horizon. IIRC you only see

Interesting point. Googled it...


So did I and found a few references to the sun being something like 5 to
10 degrees below the horizon. Now 5 degrees is 20 mins with sun coming
straight up. It will be longer with the sun rising at an angle.

As it was small patch could it have been a sun dog?
