Astral Divination

You send your request to the stars, pleading them to find whom you seek. You cast a Divination spell, that shows you the location of a target by lighting up a bright star in the sky above the target. This effect lasts for 1 minute. The target must make a WIS save: on a failed save a bright star lights up in the sky above the target, and the target is not alerted about the spell, on a successful save the spell fails and the target is alerted of the attempt.
