We have obtained 26 372 CCD frames in the B, V , and I c filters for 81 RR Lyrae stars in 2008-2010, using the 76-cm telescope of the South African Astronomical Observatory and the 40-cm telescope of the Cerro Armazones Observatory, North Catholic University (Chile) using an SBIG ST-10XME CCD camera. For 12 of these RR Lyrae stars, we also obtained 337 brightness measurements in the B and V bands in 2000-2001 using the 60-cm telescope of the High Altitude Mt. Maidanak Observatory (Republic of Uzbekistan). We present tables of observations, light curves, and improved lightcurve elements for all these RR Lyrae stars. The Blazhko effect was detected for SU Hor.
