Caption: Figure 1.

Image of the MACS J1149 galaxy-cluster field and the locations and timing of the appearances of SN Refsdal. A first appearance occurred according to model predictions in the host galaxy image at the upper left in the late 1990s but was missed. We detected images S1–S4 in an Einstein-cross configuration in 2014 November (Kelly et al. 2015). Following this appearance, lens modelers predicted the SN’s reappearance, which was detected in late 2015 (Kelly et al. 2016c). Inset at upper right shows a co-added WFC3 IR F125W image of the field following the reappearance of the SN in image SX.
