Left: contrast curve from the 2020 Zorro Observations of HD 212330/TIC 259291108 from the ExoFOP archive. Right: reconstructed image from the 832 nm filter. S. R. Kane et al. (2019) reported a companion at 0﹩\mathop{.}\limits^{\unicode{x02033}}﹩77 with a position angle of 62° and a magnitude difference of 5.5 at 880 nm using DSSI on Gemini South in 2017. The red box highlights our possible detection of the same companion in this reconstructed image from 2020.
