Caption: Figure 3.

UV and optical light curves from Swift and ground-based facilities. The arrow marks the last nondetection, which was in r band. The red cross marks the peak of the r-band light curve, which is 16.3 mag at ﹩{\rm{\Delta }}t=4\,\mathrm{days}﹩. The full set of light curves is shown as gray lines in the background, and each panel highlights an individual filter in black. We correct for Galactic extinction using the attenuation curve from Fitzpatrick (1999) and ﹩{E}_{B-V}={R}_{V}/{A}_{V}=0.01﹩ for R_V = 3.1 and A_V = 0.029 (Schlafly & Finkbeiner 2011).
