[vsnet-alert 23924] Re: PNV J17561375-2942546: possible nova (11.5 mag) in Sagittarius

[AYANI Kazuya]

Akazawa-san, Funao, Kurashiki, Okayama, Japan, obtained a low-resolution  
spectrum (resolution about 1.6 nm at H-alpha, range 380-790 nm) of this  
PNV with a 0.35m telescope, DSS-7 and ST402 on Feb. 1.888 UT. He says that  
it shows prominent H-alpha emission line, whose half width (which is not  
deconvolved by the instrumental width) and the equivalent width are 1600  
km/s and 11 nm, respectively. which show the characteristics of a nova.

Clear skies,
Kazuya Ayani
former staff of Bisei Astronomical Observatory
