Dear Taichi Kato,

In the last days I have seen the discussion in the VSNET on the nature
of V2323 Sgr. We observed this star in the course of a photometric and
spectroscopic program on southern and equatorial irregular variables
and suspected cataclysmic variables (article in press in the Astronomy
& Astrophysics Suppl. Series). Our spectroscopic observations indicate
that V2323 Sgr has a late type spectrum (prominent TiO bands in the
optical region) with emission lines of Balmer series (the emission are
weak or absent when spectrum become later). The spectrum is not typical
of a CV or symbiotic star. Possibly, this star is some type of
semiregular variable or a Mira.
