CMC12 192756.2+000128  -  Mira Variable

RA 19h27m56.25s sd 0.090" Dec +00 01' 28.5" sd 0.200" (ICRF)

r'_CMT_ 15.684 sd 1.381 from 4 photometric observations

Three red NOFS survey archive plates confirm marked variation. 
Interestingly the three blue plates do not do so.  There is a very close
neighbouring star that is lost on the red plates when this object is
bright.

In the case of contemporaneous blue and red plates, the object is
distinctly brighter on the red plate.  Very bright on far red plates. 
It is also an IRAS source.
