ADC_Keywords: Magnitudes ; Stars, variable Abstract: We searched the CCD/Transit Instrument (CTI) survey databases for RR Lyrae variable stars. The CTI images a strip of the sky with a narrow spread of declination over all right ascensions. The resulting survey area covers a large range of both Galactic latitude and longitude, amounting to approximately 50deg^2. We detected a total of 42 RR Lyrae stars to a faint limiting magnitude of V=19. Thirty-four of these RR Lyae stars are newly discovered.
