   This star is the 14.5-mag star Takamizawa noted.  The scale on his films
was not enough to separate them, but he noted that the 14.5-mag star was
never observed as bright as 14 mag on his previous films.

   The star is recorded by 2MASS survey, which gives J=12.50, H=11.75,
Ks=11.51, not particularly red among neibouring stars.  This color
certainly excludes a Mira-type variable.
