SUPERNOVA 2009md IN NGC 3389
     J. Sollerman and M. Ergon, Stockholm University; C. Inserra, Istituto
Nazionale di Astrofisica; and S. Valenti, Queen's University, report on
spectroscopic observations (range 350-900 nm, resolution 0.8 nm) of 2009md
(cf. CBET 2065) obtained with the Nordic Optical Telescope (NOT; + ALFOSC)
on Dec. 8.27 UT; the observations were obtained by P. A. Wilson (NOT), S. Jon
Juliusson (University of Iceland), and four high-school students:  H. Holma
and M. Ingemyr (Rymdgymnasiet, Sweden), O. Saxen (Katedralskolan i Abo,
Finland), and L. Haukanes (Stord vidaregaande skule, Norway).  The fully
reduced spectrum of 2009md shows it to be a young type-II supernova.  Cross-
correlation of the spectrum with a library of supernova spectra using the
"Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024)
shows it to be most similar to the type-IIP supernova 2005cs close to maximum
light.
