We’ve already seen halos on the Sun and the Moon here in Universe Today. The explanation for both events is pretty much the same. Halos appear to surround the Sun or the Moon as a result of the refraction of light through the ice crystals in cirrus clouds.
The photo above shows a halo on the Sun. It was captured by Kevin Jung on November 18, 2011 using a Canon EOS 40D. Check out more of Kevin’s work here.
More halos below…
Jason Ahrns caught not two, but three birds with one stone with this photo he captured on October 23, 2010 in Alaska. There’s a stream of the aurora, moon halo and a meteor trail all featured in one photo. Jason used a Nikon D5000 camera in taking this photo.
Christopher Farmer captured this photo of a solar halo over the Grand Palance in Bangkok, Thailand on September 5, 2011 using his Canon 450D. Check out his Flickr page for more photos.
