Caption: Figure 6.

HST F814W image taken post-outburst in 2014 July with the location of the X-ray source from Chandra (0.″47 radius, dotted error circle; Binder et al. 2016). The solid circle centered on the optical source has a diameter of 0.″8, the size of the widest X-shooter slit that we used, showing that there are no other sources contributing significantly to the optical/NIR emission.
