NOVA SCORPII 2010
     K. Ayani, Bisei Astronomical Observatory (BAO), writes that a low-
resolution spectrum (range 400-800 nm; resolution 0.5 nm at H-alpha) of the
probable nova reported on CBET 2183 was obtained with the BAO 1-m telescope
on Feb. 23.88 UT.  This shows prominent H-alpha emission with P-Cyg
absorption upon a red continuum.  The FWHM and equivalent width of the
H-alpha emission component are about 1800 km/s and 70 nm, respectively, and
the absorption bottom is blueshifted by 1600 km/s with respect to the
emission peak.  The spectrum also shows emission lines of H-beta and Fe II
(multiplet 42), which are weak and probably due to large interstellar
extinction.  These features show that the new object is a "Fe II"-type nova.
