Abstract

Visual light curves of the author's observations are pesented for the following nine neglected Southern long period Mira- and Semiregular-type variables: U For, YY Cen, TW Sco, GH Ara, RZ Pav, SY Sco, DF Pav, BR Tuc, and RU Phe. Values for O-C and M-m and visual ranges are also given, as are new periods for YY Cen (365 d), DF Pav (~180 d), and BR Tuc (~218 d). The author's results are compared with those values in the General Catalogue of Variable Stars (GCVS).
