Dear Jackie, Rather more common are mock suns, or sun-dogs, which are either side of the sun. Some dramatic examples are in: https://en.wikipedia.org/wiki/Sun_dogs <https://en.wikipedia.org/wiki/Sun_dogs>
They are at 22º either side of the sun, and if you know when and where to look, and in the right cloud conditions you will them quite frequently. I often see them when travelling.
