TL;DR: In this paper, a sample of 6 LR Type II SNe (SNe II), 3 of which were discovered and observed by the Palomar Transient Factory (PTF) and 3 observed by Caltech Core-Collapse Project (CCCP).
PTF10ops - a subluminous, normal-width lightcurve Type Ia supernova in the middle of nowhere
Kate Maguire,Mark Sullivan,R. C. Thomas,Peter Nugent,D. Andrew Howell,Avishay Gal-Yam,Iair Arcavi,Sagi Ben-Ami,S. Blake,János Botyánszki,C. Buton,J. Cooke,Richard S. Ellis,Isobel Hook,Mansi M.

Ofek,Dovi Poznanski,Robert M. Quimby +28 more
TL;DR: PTF10ops is a Type Ia supernova (SN Ia) whose lightcurve and spectral properties place it outside the current SN Ia subtype classifications as discussed by the authors.
