Top: total intensity SPHERE/IRDIS-DPI image of WaOph 6. Encircled in red is the CC. Bottom: astrometry plot of the CC of WaOph 6. The markers show the position of the CC, at the initial HST epoch, and further in time at the SPHERE epoch. The black curve traces the path a stationary background object would have followed relative to WaOph 6 between the two epochs.
