nothing wrong with that Andrew, and it certainly does count as as a sundog/parhelia, that is quite common to only see one, and not the pair, in fact that is the norm IMO.
Sometimes when there is a chance of a pair, thicker lower cloud will obscure its twin, and sometimes move and cover the other one, while revealing the other one previoulsy covered lol
anyway nice one, thanks for posting! love it, love he transient stuff, as opposed to the usual sitting duck stuff
