Answer 1

a sun dog.

"A sun dog or sundog (scientific name parhelion, plural parhelia, e.g. "with the sun") is a relatively common halo, an atmospheric optical phenomenon mostly associated with the refraction of sunlight by small ice crystals making up cirrus or cirrostratus clouds. Another term used is sunbow (an arch resembling a rainbow made by the sun shining through vapor or mist)."

There is also a halo/icebow, which forms from refraction of ice crystals.
