Abstract:
    We report discovery of 3 new faint variables in the globular cluster
    NGC 288: 2 SX Phe stars and 1 contact binary. Both SX Phe variables
    are blue stragglers. The contact binary is located below cluster
    turnoff, slightly to the red of the main sequence. New photometry of 6
    previously known variables is also presented. We note that 26 out of a
    total 43 SX Phe stars identified recently in ω Cen and NGC 288
    exhibit V-band light curves with full amplitudes smaller than 0.10mag.
    The sample of known SX Phe stars is likely to be significantly
    incomplete in regard to the low amplitude variables.
