Recently, Hornoch and Vrastil (2012, ATel#4314) suggested that
M33 nova candidate PNV J01325510+3047283, discovered by the Lick
Observatory Supernova Search (LOSS), was a likely a LPV in M33.
We searched the public data release of the Catalina Surveys
(CSDR1) and discovered
the source to be a good match to source CSS J013255.0+304730
(RA=01:32:55.0, Dec=+30:47:30.5). The object's lightcurve exhibits
significant variations (> 2 mags) reaching V~18.1. Extraction
of additional archival CSS
photometry and images dating back to Jan 13th 2004 show the
source to be a long period variable with a period of around 900 days.
