                PHOTOMETRIC LIGHT-CURVE OF RV OCT


      The photographic plates used are from the Bamberg South-
African Station. A photometer with iris diaphragm after Becker has
been employed (W. BECKER and C. BIBER, ZfA 1956, vol, 41, p. 52).
In deriving the light-curve (see figure), maximum brightness and
amplitude have been adjusted to the values given in the General
Catalogue of Variable Stars, Moscow 1958. The mean error for the
value derived from one plate is about +- 0m.05.

     As W. STROHMEIER and H. OTT reported (Information Bulletin
on Variable Stars, Number 38, 1963), RV Octantis is an RR Lyrae
variable of type ab. The estimated period derived by W. STROHMEIER
had to be slightly shortened. The elements of RV Oct are:
