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 50 deg^2^. We detected a total of 42 RR Lyrae stars to a faint limiting magnitude of V = 19. Thirty-four of these RR Lyrae stars are newly discovered.
