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.
V993 Sgr is 2.4 arcmin from MisV0841. No star brighter than 14.5 mag was detected at the cataloged position of V993 Sgr. However, V993 Sgr is an eclipsing variable star between 13.1 - 14.1 mag. On the other hand, MisV0841 is probably a red variable, considering the color in the USNO-A2.0 catalog and the identification with IRAS 17563-3241. Therefore, MisV0841 is probably another new variable star.
