Left: jet-axis PA of GRS 1915+105 measured between 1994 and 2025 (see Table 3). Right: since 2023, the orientation of the jet has exhibited significant variations over a PA range of 118–188. In both panels, the horizontal dashed gray lines and shaded regions indicate the mean PA of 147 ± 8 for the southeast–northwest jet (L. F. Rodríguez & I. F. Mirabel 2025).
