We present R-band light curves of Type II supernovae (SNe) from the Caltech Core-Collapse Project (CCCP). Our light curves show a relatively long rise time (>20 days) followed by a slow decline stage (0.01-0.15 mag day, We find that a narrow P-Cygni profile in the hydrogen Balmer lines appears to be a ubiquitous feature of SNe IIn. ![]() Therefore, these events are representative of the observed population of SNe IIn. The CCCP SN sample is unbiased to the extent that object selection was not influenced by target SN properties. Here, we study the four SNe IIn observed by the Caltech Core-Collapse Project (CCCP). Type IIn supernovae (SNe IIn) are rare events, constituting only a few percent of all core-collapse SNe, and the current sample of well-observed SNe IIn is small. ![]()
