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. Here are also visible planets Jupiter and Saturn as faint white dots. 1st décember 2001.
