The light curve displays three distinct peaks, the brightest of which is at $M_{R} \\sim -15.0$ mag. The post-discovery evolution is consistent with the ejecta from the outburst interacting with two distinct regions of circumstellar material. The 0.5 - 2.2 $\\mu$m spectral energy distribution at -740 d is well-matched by a single 6700 K blackbody with $\\log(L/L_\\odot) \\sim 6.1$.
