* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima, Okayama, Japan, discovered new variable stars MisV1428 - MisV1431.

They were 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. Their variations were confirmed by Yoshida and Nakashima.

* Special Notes

Stefan Huemmerich and Klaus Bernhard reported the LINEAR and Catalina Sky Survey data revealed it is an Algol-type eclipsing variable with a chromospheric activity (EA/RS type), with a period of 0.4629 days, brightness range of 14.35-14.90 mag(CV). It exhibits a long term mean magnitude change, probably caused by a long period spot cycle (light curve, phase diagram).
