Epoch 102 (2016-09-05) VLBI 7 mm image, showing total flux intensity (contours) and polarized flux intensity (color scale). Black line segments overlaid in the image represent the EVPA. The green ellipse in the lower left corner represents the beam size. The image showcases component B5 close to the peak of the 2015 flaring episode, demonstrating how the polarization angle is aligned with the direction of propagation.
