Noctiluscent Cloud

....Out till 2.30 AM looking for Aurora Borealis, but the northern sky refused to become dark enough to allow it to show properly.
On closer inspection of my shots, I discovered the time wasn't entirely wasted.
These milky looking whisps are 30 - 50 miles up at a temp of - 125C.

Big blast from the Sun is heading our way NOW, so get out over the next few nights to capture the Aurora!
