Summary For stable, mature sunspots, the flow in the sunspots is pretty consistent in the range from -0.5 Mm to the photosphere; Except for the flow in the sunspots that seems to switch from inflow to outflow earlier at the photosphere than at -0.5 Mm. For emerging, complex sunspots, the outflow surrounding the sunspots are consistent within -0.5 Mm and the photosphere; part of the shear motion along the magnetic neutral lines is consistent within that range; Inflow in the sunspots and rotation motion seem not to be agreeable at -0.5 Mm and in the photosphere.
