Scientific paper

A search for H-alpha-emission objects covering an area of 25 sq deg in the Ara region of the Milky Way resulted in the discovery of 124 objects. The limiting magnitude of the survey is about R equals 14.5. More than two-thirds of the objects were not previously known. UBV photographic photometry was also obtained for objects brighter than V equals 15.4, B equals 16.3, and U equals 16.4; the photometric data allow us to make a preliminary discussion of the early-type objects which suggests that most of them lie beyond the Sagittarius arm.
