[vsnet-id 258] IDs from MISAO observations

[Seiichi Yoshida <comet@aerith.net>]

Dear colleagues,

Here I report the revised astrometry and identifications of some
variable stars found in the course of the MISAO Project. We confirmed
the variability of all stars here on the unfiltered CCD images taken
by Nobuo Ohkura, Okayama, Japan, and KenIchi Kadota, Ageo City, Japan.

Taichi Kato pointed out that the position of V354 Vul is revised in
IBVS 4450. The position of V354 Vul = LD 143 in IBVS 4450 is
R.A. 19h50m10s.47, Decl. +22o32'17".0 (J2000.0). There is a 16-mag
star at the position on Ohkura and Kadota's images, that shows no
significant variability. And it is too faint because V354 Vul is a
Mira type variable star with a range of 13.2 - [15.2 mag(V). We
discovered a variable star with a range of 12.2 - 14.4 mag at
R.A. 19h50m08s.67, Decl. +22o32'17".8 (J2000.0), 25 arcsec from the
position, that must be identified with V354 Vul.

John Greaves pointed out that the position of GU Sge is revised in
IBVS 4790. The position of GU Sge in IBVS 4790 is R.A. 19h59m04s.88,
Decl. +21o07'55".9 (J2000.0). But our astrometry using the USNO-A1.0
shows the position is R.A. 19h59m05s.04, Decl. +21o08'13".1 (J2000.0), 
that is 17 arcsec from the position.
