This is a 'ring around the moon' or lunar halo. Overexposed in the centre of the frame, is the Moon. Lunar halos are caused by moonlight being refracted by cirro-stratus clouds. These thin clouds are located very high in the atmosphere, and are composed of ice crystals. They bend light at a 22 degree angle, which creates a halo that is 44 degrees in diameter.
