Did you see the halo around the sun that also had a couple of "extra" suns in it?
Then you saw an optical phenomenon called a 22 degree halo and sundogs.
The halo itself goes around the sun at a distance from the sun of 22 degrees.
If the alignment of the cloud's ice crystals are random, the halo will form. If, as often happens when the ice crystals sink, they become more aligned in the horizontal, they refract or bend the sun's light horizontally, creating the brighter spots on each side of the sun on the halo called "sundogs."
