Abstract

During a study of the δ Scuti star V1393 Centauri by digital single lens reflex photometry, it was found that two of the chosen comparison stars were variable. This paper reports the subsequent investigation of one of them, the class A star HD 121191, which revealed that it is a candidate δ Scuti star with a period of 0.046282 d and an amplitude of 0.048 magnitude in V.
