Lunar Halo

A lunar halo observed during the “Super Moon” event, or the largest full moon in 18 years, which occurred on March 19, 2011. This image was taken with a point-and-shoot camera at the Sunken Garden in UP Diliman. The 22-degree halo surrounding the moon is caused by the refraction of moonlight through the edges of six-sided ice crystals in high-altitude cirrus clouds. Since blue light refracts more than red, it is always colored blue on the outside and red on the inside. Such phenomenon may also be observed around the Sun.
