Notes. aWe combined the deep non-detection (21.0 mag) and detection (20.2 mag) on unfiltered images (Wood-Vasey et al. 2003) with filtered photometry (Anderson et al. 2014). The very blue spectral energy distribution at early times suggests the effective wavelength of the unfiltered images corresponds to a blue band, leading us to adopt the V-band. Whether we combine the unfiltered data with V or B band photometry is inconsequential, however, given the significant magnitude difference between the first detection and the peak (∼3.5 mag). Because the first detection does not have a reported uncertainty, we assumed a significant error of 0.5 mag. (1) Anderson et al. (2014); (2) Wood-Vasey et al.
