Light curves of HBC 722. Filled dots are from Paper I and this work, plus signs are from Semkov et al. (2010), Semkov et al. (2014), Miller et al. (2011), Sung et al. (2013), Antoniucci et al. (2013), and from the AAVSO database¹. Mid-IR data points are either from WISE (filled squares) or from Spitzer (filled dots). For clarity, the B, V, I, J, H, K_S, [3.6] and [4.5] light curves are shifted along the y-axis. The vertical dashed line marks the epoch when our near-IR LIRIS spectum was taken, while the vertical dotted lines indicate the time of our optical GTC/OSIRIS spectra.
