Variable star in Leo.

AYANI K. and KATO T.

Abstract (from CDS):

K. Ayani, Bisei Astronomical Observatory (BAO); and T. Kato, Kyoto University, report that they obtained spectra (range 400-800 nm; resolution 0.5 nm) – with the BAO 1.01-m telescope at Ibara, Okayama, Japan, on Nov. 21.8 UT – of the variable star in Leo that was announced on CBET 746. The spectra show characteristics of a dwarf nova in outburst; H-beta and H-gamma lines are in absorption on a blue continuum, and there appears to be an emission component embedded within the absorption component of H-alpha. There are no other strong emission lines.
