Radio flux density measured over time at three different frequencies: 2 GHz (green circles), 5 GHz (blue triangles), and 8 GHz (purple squares). The data were obtained using VLBI observations and plotted against the modified Julian date (MJD). Error bars indicate uncertainties in the flux measurements at each frequency. The flux densities were calculated by integrating the emission above a 3-sigma threshold within the source region for each epoch and frequency. This shows the flux variability and evolution with time, with an overall increasing flux at 2 and 8 GHz.
