* Discovery Information

It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Ken-ichi Kadota, Ageo City, Saitama, Japan, then confirmed by Seiichi Yoshida.

It is only 2.1 arcmin from KY Sgr, nova in 1926. However MisV0645 is probably another new variable star.

* Special Notes

Taichi Kato pointed out that KY Sgr, a nova in 1926, is close, 126 arcsec from MisV0645.

However, Seiichi Yoshida found it on the DSS 1 and DSS 2 images, so it will not be a cataclysmic variable. But it looks brighter on Bj-band image than on R-band image.
