Optical light curves of SNe 2004ek, 2004em, and 2005ci. Diamonds indicate CCCP photometry, squares indicate photometry from Tsvetkov (2008) for SN 2004ek and from Kleiser et al. (2011) for SN 2005ci. For SNe 2004ek and 2004em, the circle indicates the discovery magnitude from Monard et al. (2004) and Armstrong (2004). The BVRI photometry from Tsvetkov (2008) was shifted by +0.1, +0.2, +0.2, and +0.1 mag (respectively), in order to match the CCCP photometry of SN 2004ek. Triangles indicate limits from prediscovery nondetections from the literature (see Table 2). The corresponding light curves of SNe 1987A (solid lines) and 1999em (from Elmhamdi et al. 2003, dashed lines) are overplotted and shifted in magnitude to match the peaks of our objects. The vertical dashed lines mark the spectroscopic epochs.
