PNV J17522579-2126215 (in Sgr)

We have succeeded in obtaining a low-resolution spectrum (R~400) of the PNV J17522579-2126215 (in Sgr) on June 28.593 UT, using the DSS-7 spectrometer attached to the 0.28-m Schmidt-Cassegrain telescope at the OUS (Okayama Univ. of Sci.) observatory. Broad and prominent emission lines of Balmer series, He I (7065), O I (7773) and Mg II (7880) can be seen on the spectrum. Balmer lines show asymmetrical profile. The FWHM of H-alpha is approximately 4100 km/s. From our result, this object is thought to be a classical nova with large expansion velocity.
