COMMISSION 27 OF THE I. A. U. INFORMATION BULLETIN ON VARIABLE STARS Number 2428 Konkoly Observatory Budapest 8 November 1983 HU ISSN 0374-0676 NEW OBSERVATIONS OF HZ Her During the period 27 August - 25 September 1983 photographic observations of the variable star HZ Her were carried out at the Byurakan Astrophysical Observatory with the 40in./52in. Schmidt telescope in U-light (ORWO ZU-21+UG1). The results of the photometry are listed in the Table. During 4h03m of the observations 12 plates were obtained, 8 of them by the method of multiple exposure, For these plates the magnitudes listed correspond to the mean values of HZ Her.

The brightness of HZ Her in U-light during our observations varied from 15.3m to 12.5m. V.V. HAMBARIAN, G.H. BROUTIAN Byurakan Astrophysical Observatory, Armenian SSR, 378433 USSR CORRIGENDUM The last six Julian days in Table I of I.B.V.S. No.2331 (9 May 1983) were erroneously given. The correct version of the Table given by Dr. O.J. Eggen is as follows: TABLE I.
