We report on new observations obtained with the Magellan Clay telescope of a tiny dust patch in the Sa galaxy NGC 3269, in the Antlia galaxy cluster. It has already been suspected to be a projected Galactic foreground cloud. In this case, a size of about 4″ and a maximum absorption of ∼1 mag in the B band would make it unique so far. We present further evidence for its Galactic nature from imaging under excellent seeing conditions (0″.3-0″.6). This dust cloud could be the first optically identified counterpart of a new type of molecular cloud recently discovered by Heithausen.
