* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima, Okayama, Japan, discovered a new variable star MisV1440.

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 Youichirou Nakashima.

Patrick Wils commented that it is rather red in the 2MASS and SDSS images and it is a long period variable. It is supported by the NSVS light curve.

Taichi Kato commented that the 2MASS color is J-H = 0.8 mag, H-Ks = 0.4 mag, which suggests a red variable.
