Tonight there is a Moon Halo or to give it the correct name a 22 Degree Halo which is used to describe the amount of light that is bending to create the effect.
It is caused by the light being diffracted twice by entering and exiting ice crystals high up in the atmosphere.
I have seen one before, but not as bright as this one, it is certainly a stunning view.
Here are a couple of photos I shot.
