* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi 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.

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.

* Special Notes

John Greaves identified with one of the binary WDS 19277+2423 = Pourteau 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 is 9.8 arcsec in 111 degree, which correspond to those of WDS 19277+2423, 9.2 arcsec in 115 degree very well. Greaves commented that Pourteau 3835B is probably MisV0968 because the position well coincides with that of IRAS, 2MASS, MSX5C data.
