Re: Possible Nova in Sgr: Kanatsu's observation

   K. Kanatsu (Matsue, Shimane, Japan) just reported the following
photographic estimates (with f200mm lens and T-Max400(120) film + PO0 filter)
of the object reported in IAUC 8113.  (Kanatsu gave the GSC number
rather than the possible nova designation; the decision is preserved in
the following data).  The object was bright in 2002 summer, indicating
that the object is likely a Mira-star, which can be identical with
V4006 Sgr.  Kanatsu did not detect other different variable star canditates
near the nominal position of V4006 Sgr.
