M. Fujii, Fujii Kurosaki Observatory; and M. Yamanaka, H. Akitaya, T. Ui, and T. Okushima, Hiroshima University, report that they obtained low- resolution optical spectra of PNV J18441516-1732310 on Oct. 6.5 UT at the Fujii Kurosaki Observatory (R = 500) and Higashi-Hiroshima Observatory of Hiroshima University (R = 400). The spectra show the absorption-lines sequence of the TiO band between 500 and 950 nm. The line profile is similar to that of an M-type star. This indicates that PNV J18441516-1732310 should be classified as a Mira-type variable star.
