This was a very distinct halo in moonlight, the exposure of about a minute was long enough to show some colour.
In the left image the head of Leo is visible through the edge of the halo.
In the right image the upper and lower tanger arcs have joined to form a distinct elliptical circumscribed halo, outside the circular 22 degree halo.
Castor and Pollux, in Gemini, are the two bright stars to the upper right of the moon.
