Strong 22 degree Halo and a Helpful Cat

A very thin and even veil of cirrus produced a fine example of this halo.

Sitting at the end of the fence the cat was in just the right place to block out the sun, and obligingly stayed still long enough!

This composite of three images shows the full halo well.

The Sun altitude was 56 degrees.
