Atmospheric Phenomenon

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. For more lunar halo images, click here.
Crepuscular rays taken from Manila Bay, Philippines on January 21, 2012. Canon 450D, ISO 100, 1/4000 sec exposure. Crepuscular rays are rays of sunlight which stream from gaps in the clouds and appear to radiate from a single point in the sky (the location of the Sun). Photo Credit: Anthony Urbano.
