I think the sun can be considered beyond "very high". If said angel was fast enough to get near the sun so it could move around without getting spotted (90 million miles or so), he would hardly have any need of hiding!
On the other hand, perhaps the sun in Dominions is much closer to the earth. Being as it's probably some god's flaming chariot, or a glowing creature or something, it may not be very high at all.
