Flying saucer caught over Edinburgh on october 2016

One day of october 2016, an impressive flying saucer was photographed over Edinburgh, Scotland. What is it?

Witness report:

Got back from Scotland and was looking at pictures we took on Cockburn Street in Edinburgh. Noticed this UFO a year later while looking at the picture

While looking at pictures from Scotland we noticed this object in the background. It doesn't look like anything I have ever seen before.
