SUPERNOVA 2007K IN MCG +06-20-50
     A. Harutyunyan, S. Benetti, M. Turatto, and E. Cappellaro, Istituto
Nazionale di Astrofisica, Osservatorio Astronomico di Padova, report
that a spectrum of 2007K (cf. CBET 812), obtained on Jan. 17.87 UT with
the 3.5-m TNG (+ DOLORES; range 340-810 nm, resolution 2 nm), shows it
to be a type-IIn supernova.  The spectrum closely resembles that of SNe
1999eb and 2003G (Asiago Supernova Archive).  Spectrum has a blue
continuum, superimposed by emissions due to H_alpha, H_beta, and H_gamma
lines.  H_alpha shows a composite profile consisting of a narrow
(unresolved) component superimposed to a broader (FWHM about 3100 km/s)
component.
