[vsnet-newvar 493] New Haseda variable (HadV62)

New Haseda variable (HadV62)

   Katsumi Haseda (Aichi, Japan) reports the discovery of a new variable
star (HadV62).  The amplitude suggests a Mira star, but the absence of
the image on the RealSky (confirmed by Haseda), likely identifications
with the blue Tycho2 (but missing on GSC) star, and the absence of an
IRAS source which is expected for this bright variable, is unusual.

   Confirmatory observations (multicolor photometry, astrometry and conparison
with DSS and other catalogs, spectroscopy) are urgently requested.

HadV62: Haseda's measurement: 183218.4 -263014 (J2000.0)

HadV62
=? USNO0600.18317531 183218.438 -263013.75 (2000.0) 11.6 14.0
=? 183218.3 -263011 (2000.0) 1132 0.27 TYC2-6865.3487.1 (11.35 0.17) (11.67 0.13)

  The object is not identical with V1901 Sgr, which is at 183216.7 -262943.5.
