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.
