[vsnet-chat 7328] New variable star MisV1351

[Seiichi Yoshida]

Dear colleagues,

I report new variable star discovery in the course of the MISAO
Project (MisV1351).

Seiichi Yoshida, MISAO Project; Ken-ichi Kadota, Ageo, Saitama, Japan;
and Kazuhiro Nakajima, Mie, Japan, discovered a new variable star
MisV1351.

It was picked up by Seiichi Yoshida from the candidates of new
variable stars detected by the PIXY system 2 from images taken by
Ken-ichi Kadota for eclipsing variable survey around Nova Cyg 2001
No.1 = V2274 Cyg in 2003 July.

Although the variation in 2003 July was very small and somewhat
doubtful, Kazuhiro Nakajima operated time series photometry on 164
nights during three years and detected its eclipse twice. Then
MisV1351 was confirmed to be a new Algol-type eclipsing variable.

Only two eclipsing events were detected on 164 nights during three
years. So the period is still uncertain. The eclipse of MisV1351 must
be very rare. Further observations are in progress.
