[vsnet-chat 973] Re: On the nature of V2323 Sgr



Dear Taichi,

I have no way of proving or disproving the cv status of V2323 Sgr, but since Seiichiro's measurements I am convinced it isn't a cv.

Hopefully someone else will confirm Seiichiro's and your measurements via V-R-I photometry or spectroscopy. 

V2323 Sgr is now on its way down (getting fainter): I expect its v (or V) magnitude to decrease more dramatically than that in R or I. 

Unless it is proven to be a cv-like object (symbiotic eventually) this will be the last I'll have seen of V2323 Sgr!


Regards,


Berto

On the nature of V2323 Sgr

   I have noticed I once obtained I-band photometry of V2323 Sgr.  The
resultant Ic=12.2, when the object was presumably in "quiescence".
From this apparent red color, I judged this star to be "not CV?" according
to my old memo.  Some more infomation on Sgr suspected CVs, which I judged
"non CV" from their colors.

V2032 Sgr  Ic=10.7
V2038 Sgr  Ic=11.7
V3462 Sgr  Ic=10.6
V3914 Sgr  Ic=9.6
