     Unfortunately you can't find this object in SIMBAD
by the usual name "M33 Var C" or permutations on that name.
The Hubble & Sandage paper doesn't help either,
since they give no coordinates.
     The best SIMBAD-valid name for the star is [HS53] C.
The position is:  1 33 35.11  +30 36 00.4  (J2000),
adopting UCAC4.  I note this is 0".13 from the Carlsberg
position, but several survey papers with less-good
astrometric solutions have offsets up to 2"-3", despite
having much larger image-scale.  The GCVS position is 3".4
in error.
     I note there is SDSS imaging but no catalogue for
the galaxy.
