The object was found on two Technical Pan films (limiting mag about 20.5) taken 1993 Dec. 27.23 and 28.24 UT. The object is only 1 mm from the side of the field. Nothing is visible on the POSS prints down to mag 19.5-20. A nearby star of mag about 16 is located at R.A. = 12h01m42s.90, Decl. = -0 24'53".9. M. Hamuy, Cerro Tololo Interamerican Observatory, reports confirmation by J. Storm (European Southern Observatory) of the presence of a new stellar object 4".2 west and 4".2 south of the galaxy's centre, as observed in B, V, and I images obtained on 1993 Dec. 29.333 UT with the CTIO 0.9-m telescope.
