This galaxy shows a bar structure clearly and is very interesting. A small stellar nucleus is surrounded by a small circular condensation, from both sides of which a faint bar structure extends. This appearance of a stellar nucleus and small core is quite common among barred spiral galaxies. An elongated halo is extensive and the direction of its elongation is slightly different from that of the bar structure.
