Cause of dark blue spot in the sky?

I just noticed a dark spot in the sky in the upper right of several photos. I looked at another picture in a different direction and it's gone.

Any idea what would cause it?

See dark dot between the two clouds at the upper right

The dot on this one is in the same place

Also in the same place

This picture is facing a different direction and the spot is gone
