We present optical photometry and spectroscopy of SN 2005ip for the first 3 yr after discovery, showing an underlying Type II-L supernova (SN) interacting with a steady wind to yield an unusual Type IIn spectrum. For the first ∼160 days, it had a fast linear decline from a modest peak absolute magnitude of about −17.4 (unfiltered), followed by a plateau at roughly −14.8 for more than 2 yr. Initially having a normal broad-lined spectrum superposed with sparse narrow lines from the photoionized… 
SN 2007od: A TYPE IIP SUPERNOVA WITH CIRCUMSTELLAR INTERACTION
SN 2007od exhibits characteristics that have rarely been seen in a Type IIP supernova (SN). Optical V-band photometry reveals a very steep brightness decline between the plateau and nebular phases of
