Coordinate Correction
The correct coordinates for the panSTARRS image of 2020crn and the magnitude readings are:
ra = 219.987389 dec = -15.457884.
Sorry for any confusion :)

PanSTARRS Photometry from May 2011
A PanSTARRS g-band image from 2011-05-04 shows a 4 or 5 pixel square at coordinates: ra=219.387389 dec=-15.457884 which might well be a likely candidate for the host system.
I calculated two magnitude values for this space which are 20.68 and 20.82. The first value 20.68 was calculated by using a 3 pixel radius aperture and the 20.82 value using a 6 pixel radius aperture. The reference star used is GAIA object id 6286727661914840576, for which I used a 6 pixel radius aperture for in both values. (Credit to Aperture Photometry Tool)
The FITS frame used is: Downloads\rings.v3.skycell.1020.017.stk.g.unconv.fits which has the date: MJD-OBS =55685.793648784. Image is attached.

Nova visible from June/July 2000
An apparent nova outburst was detected by Sam Deen which occurred on 30 June and 1 July 2000, using archival r-band images from the La Silla Observatory's 2.2-meter MPG/ESO Telescope at coordinates ra=14:39:56.989 dec=-15:27:28.04. The images were originally taken as part of a program to follow-up the Trans-Neptunian Object 2000 JH81. On 30 June, the transient appears to have an r-band magnitude of 21.5 and by 1 July it had brightened to an r-band magnitude of 19.4. In a 360-second exposure in the wide-band GRI filter by the Canada-France-Hawaii Telescope, a point-like source of roughly magnitude = 25 is visible at coordinates ra=14:39:56.971 dec=-15:27:27.94.
