We note significant (if not complete) flux contamination from the host galaxy (SDSS g-band magnitude ~15), the center of which is roughly 12" offset from the reported transient position. Y

Correction: The observation was performed using a SeeStar S50 integrated smart telescope (50mm f/5, Sony IMX462 sensor) instead of the previously reported instrument.
