Corwin's Notes
=====
NGC 3180 is part of the northwestern arm of NGC 3184. For a long time, I
thought that the number applied only to an HII region or star cloud in the
northern part of the arm. But there is a sketch in LdR's 1861 monograph that
shows the spiral arm connecting NGC 3180 and NGC 3181. It has both as patches
extended along the arm, with NGC 3180 at the northern end and NGC 3181 at the
southern. I've left the positions of the HII region -- actually a line of
three knots, the southern perhaps a star -- and the star cloud in the table to
differentiate them from the arm itself.
Steve's Notes
=====
NGC 3180
48" (4/4/11): A small HII knot with a stellar core was visible 1.8' NW of the nucleus of NGC 3184. This small knot is within a larger, slightly brighter portion of the long, sweeping arm (shown on the sketch at Birr Castle) that wraps around the core of NGC 3184 on the south side before winding north on the west side and ending near NGC 3180.
