[vsnet-newvar 1698] CMC12 191325.0+011812 is a Mira Variable

[jg@jgws.freeisp.co.uk]

CMC12 191325.0+011812  -  Mira variable

r'_CMT = 14.173  sd 1.0 for 5 observations

Variability shown from 5 red, and independently from 5 blue, survey
plates sourced via NOFS image and catalogue server at
www.nofs.navy.mil/data/FchPix.  The blue plates actually don't always
show it, whilst it is quite bright on one blue plate.  Invisible on the
blue DSS1 plate, whilst easily seen on the same date DSS1 red plate. 
Brightest on far red plates, an IRAS source rated at 78% probability of
variability, and only detected in band A by the MSX5C experiment,
suggestive of silicate emission.

In a crowded field, with the star obscuring nearby stars when at
brightest, especially on red plates. Thus the exact identification with
the very adjacent USNO B1.0 and GSC2.2 candidates is uncertain.
