* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1147.

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.

The identification is researched by Taichi Kato (Kyoto University), John Greaves (the United Kingdom), and Seiichi Yoshida.

* Special Notes

It attracted attention due to the identification with a H-alpha emission star HBHA 65-53. The campaign in "vsnet-campaign-unknown" and the MSDG observing campaign were launched, and many visual observers have been monitoring it. It did not show any evident variation in the first half of 2002, however, it showed frequent deep eclipse-like fadings in the latter half of the year. Based on the spectrums taken by Kenzo Kinugasa and Mitsugu Fujii, Taichi Kato revealed MisV1147 is a young stellar object, a Herbig Ae/Be type star.

The V-Ic value is different between 2002 January and the period after 2002 October. But the reason is still uncertain.
