Radial Velocity Studies of Southern Close Binary Stars. II. Spring/Summer Systems
Radial velocity measurements and sine-curve fits to the orbital velocityvariations are presented for 14 close binary stars, S Ant, TT Cet, TWCet, AA Cet, RW Dor, UX Eri, YY Eri, BV Eri, CT Eri, SZ Hor, AD Phe, TYPup, HI Pup, and TZ Pyx. All are double-lined binaries, and all exceptthe last one are contact binaries. The orbital data must be consideredpreliminary because of the relatively small number of observations(6-12), a circumstance that is partly compensated by the good definitionof the broadening functions used for the radial velocity determinations.Based on data obtained at the European Southern Observatory.

Amateur Variable Star Observing in Japan
Activities and publications of various astronomical groups in Japan aredescribed.

CU Eridani — A suspected variable
Photometric observations of CU Eridani, recently classified asnon-variable, indicate it to be a variable star. The observations arenot sufficient to indicate the type of variability but CU Eri does notappear to be an eclipsing star.
