[vsnet-chat 2428] MisV0701 = planetary nebula PK32-3.1

[Seiichi Yoshida <seiichi@muraoka.info.waseda.ac.jp>]

Dear colleagues,

I am Seiichi Yoshida working on the MISAO Project.

Taichi Kato pointed out that MisV0701, one of the new variable stars
discovered in the course of the MISAO Project, is identified with a
planetary nebula PK32-3.1. The catalogued position of PK32-3.1 is 47
arcsec from MisV0701.

If the identification is correct, this will be a rare object. It may
be a ZAND type object. Further observations and past information are
encouraged. 

This object is at R.A. 19h00m31s.77, Decl. -02o12'20".4 (2000.0),
which must be in the survey area of FASTT or TASS project. Do you have 
any data of this object in the past?

Best regards,
