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