Is SN2010lp a member of a new class of underluminous type Ia supernovae?

Abstract:
We present preliminary results of the observational campaign on SN2010lp carried out by the Millennium Center for Supernova 
Science (MCSS).
This SN is peculiar is several aspects. It has a low luminosity, red colors and absence of a secondary maximum typical of 
SN1991bg-like SNe, but it displays a slow rice to maximum and also a  slow post-maximum decline.
The SN2010lp  spectra  resemble that of SN1991bg-like objects, but differences are present, also with SN2002cx-like SNe. We 
use the well sampled high quality spectral and photometric evolution of SN2010lp as a template to search for objects with 
similar characteristic, finding indications for a new class of underluminous SN Ia.
