Nothing is visible at this location on the ESO "B" survey or in the photograph of this galaxy in Vickers and Wassilief's *Deep Space CCD Atlas: South*, although a very faint knot appears in the position of the star in the blue survey. The existence of the new star was confirmed visually within a few minutes by D. Nitschki, using the same telescope, and within 20 minutes by S. Quirk using his 0.31-m reflector (+ Gstar-ex CCD, 2-min unfiltered exposure); a measurement of the variable via Astrometrica software yields red mag 14.3 and R.A. = 14h18m25s.6, Decl. = -43o22'54".
