Compilation of deconvolved NACO images cut to the central ±400,mas. The small circle in dark red marks the position of S29 on its orbit (dark red ellipse) in each panel. The orange data points are the 2019 and 2021 GRAVITY measurements. Evidently, S29 can be traced consistently over two decades. We note that around 2015 - 2017 the star is confused with other stars, such that the astrometry becomes unreliable, but the identification remains unambiguous.
