About this image

A night of exceptional seeing and the same was true for Uranus. Even the colour image shows a hint of light shading for the Northern hemisphere. If anyone can identify my question mark object I'd be grateful. My star chart doesn't have it and it is between two fainter moons beyond my scope's resolution.

I believe it is Gaia EDR3 55974354560610304, which is magnitude G=16.813(3), RP=16.242(7), consistent with it being fainter and redder than UCAC4-542-006359.

Identified by locating Oberon at 19:52UT, finding your UCAC4 star and then the unknown by examining the DSS2 image in AladinLite. That gave a position good to an arsecond or so, making it very easy to find in VizieR

I go into such detail so that others may learn my approach to solving these sorts of problems.

Aka 2MASS 03233311+1819538
