Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and
KenIchi Kadota, Ageo, Saitama, Japan, discovered a new variable star
MisV0968.

It was picked up by Yoshida from the candidates of new variable stars
detected by the PIXY system from images taken by Ohkura comparing with
images taken by Kadota. Kadota and Yoshida judged it as a real
variable star.

The magnitude are measured automatically by the PIXY system. Image
observers' names are noted after "Mis".

John Greaves pointed out that this object is the secondary star of the
binary WDS 19277+2423 = Pou 3835, the pair of 13.6 mag and 13.8 mag
stars. The cataloged position of WDS 19277+2423 is 48 arcsec from
MisV0968. But the separation and position angle of MisV0968 and a
nearby star USNO-A2.0 1125.12713797, R.A. 19h27m43s.603,
Decl. +24o23'31".07, 13.8 mag(R), 15.2 mag(B), is 9.8 arcsec in 111
degree, which correspond to those of WDS 19277+2423, 9.2 arcsec in 115
degree very well (Pourteau, M. A., Paris Catalog, Zone +24 degrees,
1933).

The identification with the 2MASS data is by Taichi Kato.
