  UM Pic was identified as a northern star of close (~ 3" separation) 
double (Reinsch et al., A&A, 291, L27, 1994).  The V-band image in
Reinsch et al. suggest that a southern star itself is also a closer 
double, which cannot be separated in DSS images.  Precise astrometry
will help to determine which is real violently oscillating object, as
well as whether it has a notable proper motion.  

  The most promising catalogued position of this object is:
GSC-2.2.1  05:31:35.596 -46:24:05.54  R=15.86 Bj=16.83
