SUPERNOVAE 2010jp, 2010jr, AND 2010js
P. Challis and R. Kirshner, Harvard-Smithsonian Center for Astrophysics
(CfA); and N. Smith, University of Arizona, on behalf of the CfA Supernova
Group, report that spectroscopic observations (range 320-850 nm) of 2010jr
(cf. CBET 2545), obtained on Nov. 14.3 UT with the MMT (+ blue-channel
spectrograph), show a smooth and very blue continuum that resembles that
seen in spectra of SN 1993J from two weeks before maximum light. A spectrum
of 2010jp (cf. CBET 2544) shows the Balmer series lines of a type-IIn
supernova; broad red wings extend to +15000 km/s, with much sharper
absorptions on the blue side at approximately -3000 km/s, which resemble the
line profiles seen in spectra of SN 2006gy. A spectrum of 2010js (cf. CBET
2546) shows the symmetric Balmer lines with widths of approximately 4000
km/s (FWZI) seen in type-IIn supernovae; the redshift for this object in UGC
4294 is z = 0.039.
