Kron-Cousins Optical Photometry of SN 2009ip
Abstract
Following a report (Smith & Mauerhan, ATel #4412) of spectral changes on 2012 Sept. 15 and 16 (JD 2456185 and JD 2456186) that suggested a transition from LBV-like eruptions (Smith et al. 2010; Foley et al. 2011; Drake et al. 2012, ATel #4334) to a true SN IIn explosion, photometric observations of the transient SN 2009ip have indicated dimming (Margutti et al., ATel #4414; Martin et al., ATel #4416) followed by significant recent brightening (Brimacombe, ATel #4423; Margutti et al., ATel #4425) of the transient.
