Remarks: This is a slow-rising object with a discovery magnitude close to the survey limit, so individual-epoch nondetections are not meaningful. It shows no history of variability in the survey prior to the initial detection, and there is no catalogued object in PS1 or ZTF reference imaging at this location.
