During a survey of the southern Milky Way with the 20/26-inch Schmidt telescope at Uppsala Southern Station a heavily reddened cluster has been found in Ara at R.A.=16h45i~i3, Dec.=-45046'.3 (1960). The region shows some very dark lanes and a few emission patches. The brightest stars in the cluster are found at V= 14 mag. No stars can be seen in the cluster region on plates reaching B =19 mag. From a preliminary photometry in infrared and visual light of 80 stars inside of circle of 2' in diameter a mean total visual absorption of 11.2 mag. has been found. The color-magnitude array indicates that the cluster is very young. It appears likely from the photographs that most of the absorption is caused by dust in the same volume of space as the cluster.
