0 a bright spot that appears in the sky on either side of the sun, caused by the refraction (= bending) of light through ice crystals in high cloud: --
The circumzenithal arc, h (commonly described, by the uninitiated, as a "rainbow"), and the parhelia of 22 degrees, e, e′, are especially brilliant in their coloration.
The closing day of the month was signalized by a brilliant meteor, a modification of the parhelion, the more interesting to us because the first we had seen.
This, on some rare occasions, is a feature of the phenomenon of parhelia.
There are, however, coronæ sometimes seen without parhelia, and vice versâ.
The parhelia are formed by the reflection of the sunbeams on a cloud properly situated.
At each point of contact occurs a parhelion which is a mock sun of brilliant colors and called a sun-dog.
Sometimes during the summer we see the parhelion, a similar phenomenon of the sun.
A beautiful parhelion was seen, one of the most complete yet observed, in the perfection of its circles and the brightness of its colors.
