I noticed that Minoru Wakuda reported in the past a photographic detection of a variable star (WSV89) in the proximity of V4006 Sgr. Although neither accurate identification nor precise position was reported by Wakuda, this detection most likely (agreed within Wakuda's typical positional error) correponded to V4006 Sgr. Wakuda-used a photographic films adjusted to V-band. All the circumstances suggest that V4006 Sgr is a Mira-star which also becomes relatively bright in the visual wavelengths (not an extremely red "infrared" Mira). The most likely candidate for the correct V4006 Sgr thus seems to agree with the star Kushida and Kushida measured. Regards, Taichi Kato
