There is a lot of science behind one of these 22-degree halos around the Sun and for it to be displayed for us to see there has to be the right shape and size ice crystals in the sky. I’m always on the look out for them when this high cirrostratus cloud in covering the sky, you also can see a lunar halo when the Moon is in a larger phase…. so as I always say keep looking up, you never know what you’ll find!
