Top left: LCT horizontal velocity field averaged over 70 min superposed on a G-band image. The length of the red arrow in the lower-left corner of the image corresponds to a velocity of 1 km s^-1, while the black box shows the dimension of the correlation window used for the LCT computation. The blue arrow indicates approximate disk center direction. Top middle: corresponding FOV in the core of Ca ii line. Top right: horizontal velocity field superposed on the median value (computed over 70 min) of LOS magnetic flux; gray lines mark the regions where the magnetic flux is equal to −100 G. The little red (middle) and black (left) squares and arrows show the starting positions and trajectories of the six tracked MMFs. Bottom Left: magnetic field strength. Bottom middle: inclination angle in the LRF. Bottom right: azimuth angle in the LRF.
