What is it Wednesday?

Well a little surprisingly after the vile weather last night I was greeted by a beautiful dawn and hardly a cloud in the sky.

One bonus of early starts is I get to see dawn most mornings.

Now for this week's WIIW.  I suspect this is an easy one, but sometimes the ones I think are easy  are the the ones that stump people.

SO without further ado, what on Earth do you think this might be?
