[vsnet-outburst 11218] Re: OT_J213806.6+261957 spectrum [Re: Bright opticaltransient in Pegasus]

[Akira Arai]

Dear All,

We also continue spectroscopy of OTJ213806.6+261957
using 1.3m ARAKI telescope at Kyoto Sangyo University.

Our preliminary spectra are shown in the following page;
http://www.cc.kyoto-su.ac.jp/~arai6a/obslog/otj2138.html<http://www.cc.kyoto-su.ac.jp/%7Earai6a/obslog/otj2138.html>

Spectral features of this object are very similar to that in the
"Plateau Phase" of GW Lib in 2008 outburst (Hiroi et al., 2009, PASJ, 61,
697).

Regards,
A. Arai,
