* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1325.

It was picked up by Seiichi Yoshida from the candidates of new variable stars detected by the PIXY system 2 from images taken by Nobuo Ohkura, and confirmed by Ken-ichi Kadota.

* Special Notes

Observations by Kazuhiro Nakajima, and the NSVS data suggest that MisV1325 is almost constant at about 14.2 mag. Observations by Nobuo Ohkura and Youichirou Nakashima also suggest that it keeps almost constant at 13.5-13.8 mag from 2001 to 2007, however, it faded only in 2000 and became fainter than 14 mag. So MisV1325 may be a RCB type variable, which rarely fades out.

Taichi Kato identified it with an emission-line star IPHAS J034712.63+571132.6. It was revealed to be a Herbig Ae/Be type star based on its color.

During 4 seasons between 2009 and 2012, it was bright by 0.5 mag only in the season of 2010-2011 based on the observations by Tsutomu Fujiwara, Adolfo San Segundo, Esteban Reina Lorenz, Diego Rodriguez, Faustino Garcia. No evident variation was observed during each season.

Nakajima's observations and the NSVS data suggest the small variation with an amplitude of about 0.2 mag.
