"There was just the weak halo until this wedge-shaped clearing pushed
in above the moon. Then the two dogs and
a bit of the parhelic circle lit
up for about 10 minutes. Shot at ISO 200 for 30sec with a Konica Minolta 7D and
Sony 11-18 lens. No diamond dust here in the desert!"
A bright moon makes halos and luckily we do not always need diamond
dust. Halos formed by ice crystals in high
cirrus clouds can be seen anywhere on Earth summer and winter.
