CO Peg: constant?

   M. Sato-san has pointed out the non-Mira nature
of this object.

   Looks constant.

CO Peg:
2MASS 214520.402 +223148.00 (2000.0) 12.549 12.252 12.146

  (This is a dwarf)

  There is a Mira star NSVS J214517.8+222754 M 12.625V (2.360) P=245
about 4' to the south.  Could it have been the original CO Peg??
