Abstract:
    We present a collection of more than 4000 UBVRI and uvby differential
    photometric measurements of the newly-discovered 12th-magnitude
    southern Delta Scuti star GSC 08613-02122. The star has a main
    pulsation period of about 4 hours with an amplitude of 0.05m in the V
    band. The pulsation amplitude is variable, and the O-C diagram reveals
    the existence of a long P∼29.5-day cycle, which possibly results
    from the beating of the main pulsation frequency with a nearby
    frequency.

Description:
    The differential magnitudes of GSC 08613-02122 are presented in
    oca.dat, and saao.dat.
    eso.dat gives the uvby photometry of GSC 08613-02122 and NGC 3293-20.
