No known variables.

Supplementary Notes 

This cluster, located in the error box of the X-ray burster MXB 1730-33,
was discovered by Liller (1977) on deep plates taken in the near IR with
the CTIO 4 metre telescope.
It was subsequently found by Tam et al. (2011) to be a Gamma-ray 
emitting cluster 

An infrared colour magnitude diagram by Ortolani et al. (2001) showed 
a red HB morphology, characteristic of a metal rich population and
Origlia et al (2002) derived [Fe/H] = -0.3, based on H-band echelle
spectra of two of the brightest giant stars in the cluster.
Thus it is unlikely that there will be any RR Lyrae or Cepheid
variables.  The cluster lies in a heavily reddened field near the 
Galactic centre with V(HB) = 24.84 according to the 2010 version of
the Harris (1996) catalogue.  Blue stragglers would be too faint to
be detected.
