Lunar Halo on Two Nights

These images were taken with the same camera settings and exposure (10 seconds) on consecutive nights. The halo on 26th February (left) was weaker, allowing more stars to show through, but there are also signs of a what may be a nine degree halo. Unfortunately there is also a smaller lens reflection inside it to confuse things, so it isn't as clearcut as the circumhorizon arc recorded on the same night.
