NEW VARIABLE STAR IN PEGASUS
     K. Kinugasa and H. Taguchi, Gunma Astronomical Observatory (GAO); and
H. Yamaoka, Kyushu University, write that a low-resolution spectrogram
(range 400-800 nm, resolution about 1.0 nm) of the variable reported on CBET
1562 was obtained on Nov. 7.6 UT with the GAO 1.5-m reflector (+ GLOWS).
The spectrum shows a smooth blue continuum with prominent H-gamma and
H-delta absorption lines.  While the H-beta is a shallow absorption, the
H-alpha appears as a weak emission line.  Both of the hydrogen features
seem to be filled by the emission core.  These characteristics suggest that
it is a dwarf nova in outburst.
