I just went outside and saw this huge 22 degree halo around the Moon. Very impressive. It even had Mars within the halo. Also notice how dark the sky is inside the halo. The images were shot with the Nikon Coolpix 4500 mounted on a tripod. Exposure time 8 seconds. I also used a wide angle lens for the coolpix. This was the first time ever I saw such a large halo around the Moon.
