SUPERNOVAE 2010gs AND 2010gj
     N. B. Andreasen, S. J. Jakobsen, and C. Heje Groenbech, DARS Summer
School -- together with J. Fynbo and J. Sollerman, Dark Cosmology Center,
Niels Bohr Institute, Copenhagen University -- report on optical spectroscopy
of SNe 2010gs and 2010gj obtained with the Nordic Optical Telescope (+ ALFOSC;
range 350-900 nm, resolution 0.8 nm) on Aug. 10.1 UT.  The fully reduced
spectrum of 2010gs (cf. CBET 2397) in PGS 65331 shows this to be a fairly
young type-II supernova with clear Balmer-line P-Cyg profiles.  SN 2010gj (cf.
2381) in PGC 190539 is instead a type-Ia supernova a month past explosion;
cross-correlation with the library of supernova spectra in SNID (Blondin and
Tonry 2007, Ap.J. 666, 1024), gives the best match for 2010gj with the
peculiar supernova 2005hk.
