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.
