Doppler-shifted Brγ line detection of D9 and D2 with ERIS in 2024. The white orbit plot indicates the trajectory of D9. Furthermore, the path and source are denoted with white arrows. In addition, we include the Keplerian approximation of D2 adapted from Peißker et al. (2020a). The magenta arrows show the source and trajectory of the dusty object D2 that was in superposition with D23 in 2019 (Peißker et al. 2024c). We expect increased confusion for both D9 and D2 from 2025 to 2027. The dusty source D23 moved out of the FOV in 2024 and is not visible in this figure.
