HST/ACS image (filter F658N) of the triple ring system of SN 1987A from 2003 January (obtained by the SAINTS team; PI: Kirshner). The slit position of the VLT/UVES observations is superposed (the slit width is 0.′′8 and PA = 30°). The numbers (1–4) correspond to the locations where we did the photometric measurements. Note how the NOR shows some irregularity with a cusp-like feature within the slit.
