Abstract:
We took a total of 1175 B, V, and Ic-band CCD frames for 11 GCVS
RR Lyr-type variables, for which only the coordinates were known.
Observations were made with the 76-crn telescope of the South African
Astronomical Observatory. We confirm the variability types, determine
the periods, and build the light curves for five objects: BL Aps
(P=0.598d), GR Pav (P=0.583d), HI Pav (P=0.643d), HZ Pav (P=0.803d),
and IR Pav (P=0.561d). The objects SY Aps (P=0.279d) and IV Pav
(P=0.408d) proved to be W UMa-type eclipsing variables; TW Aps
(P=0.149d), an SX Phe-type variable; TT Aps (P=482d), an SRD-type
semiregular variable, and SW Aps and GI Pav, constant stars.
