Outskirts of the early-type galaxy NGC 3316, located E of the core. The g-band region centred on NGC 3316 is shown in the left panel. We mark the prominent stellar stream on the SW side of the galaxy. The 2D model obtained from the isophote fit is shown in the middle panel. The right panel shows the residual image, where the 2D model (middle panel) is subtracted from the parent image (left panel). The stellar stream seems to be connected with a bright knot on top of it. Both features might be the remnant of dwarf galaxy, disrupted in the potential well of NGC 3316.
