* 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.

* Special Notes

A very faint red variable in very crowded field. The USNO-A2.0 shows the color as B-R=4.0 mag. John Greaves commented that the star is only found on red E plate, and not found on blue O plate, though both plates were on the same day, which suggests this star is very red.

On the MISAO images, the position of MisV0855 looks slightly different between in bright and faint state at a glance. That is because MisV0855 is not visible when it becomes faint, instead only a star about 10 arcsec southeast of MisV0855 is visible.
