INFORMATION BULLETIN ON VARIABLE STARS NUMBER 664 Konkoly Observatory Budapest 1972 April 24 Veroffentlichungen der Remeis-Sternwarte Bamberg Astronomisches Institut der Universitat Erlangen-Nurnberg Band X, Nr. 101 NEW FAINT SOUTHERN VARIABLE STARS On sky patrol plates taken at the Southern Station of the Dr.-Remeis-Sternwarte Bamberg, at the Boyden-Observatory, Bloemfontein, South Africa, further 12 faint stars were found to be variable (11 new stars and 1 confirmation of an already mentioned Sonneberg-Star in the Catalogue of Suspected Variable Stars). The brightness of these stars were obtained from the Harvard-Groningen-Atlas, Selected Areas (edition, 1965 by A. BRUN and H. VEHRENBERG). Finder-charts are 1deg in declination. South is up. max.
