Our goal is to investigate and understand the physical processes behind the variability associated with the NIR flaring emission from Sagittarius A* (Sgr A*). We found a correlation between the modulations of the observed flux density light curves and changes in polarimetric data. Correlations between intensity and polarimetric parameters of the observed light curves as well as a comparison of predicted and observed light curve features through a panttern recognition algorithm resulted in the detection of a signature of orbiting matter under the influence of strong gravity. This pattern is detected statistically significant against randomly polarized red noise.
