The Ks- and H-band observations taken on 22 Jan 2021 (UT; PI: Crepp; Program ID: D313) show an object 0.22 arcseconds from G 250-34 at a position angle of 328deg and {Delta}{Ks} = 2.9 mag. No other high-resolution observations were found in other archives to help confirm or refute this possible companion. --------------------------------------------------------------------------------
