Stellar orbits at the Galactic Center provide a very clean probe of the gravitational potential of the supermassive black hole. They can be studied with unique precision, beyond the confusion limit of a single telescope, with the near-infrared interferometer GRAVITY. Imaging is essential to search the field for faint, unknown stars on short orbits which potentially could constrain the black hole spin. Furthermore, it provides the starting point for astrometric fitting to derive highly accurate…

Backwards prediction of the GRAVITY data for S29GRAVITY leads to a position in March 2007 compatible with the position of S29NACO. The black points show the GRAVITY data from 2021 and 2019
