Corwin's Notes
=====
NGC 5144. This is sometimes interpreted as a double galaxy, but appears to me
to be simply a late-type spiral with a superassociation. In my previous
releases, I had the main galaxy listed as "NGC 5144A" and the superassociation
as "NGC 5144B". I've changed these now to "NGC 5144" and "NGC 5144 knot" for
consistency with my usual naming conventions.
Steve's Notes
=====
NGC 5144
24" (6/4/16): at 375x; moderately bright, irregularly round, fairly small, 0.7'x0.6', mottled or uneven surface brightness but no distinct core. Situated at the midpoint of a mag 11.8 star 1.9' NNW and a mag 13.7 2.0' SSW.
NGC 5144 apparently has a merged companion at the south edge, identified as NGC 5144 NED01 = LEDA 200298. It appeared as a quasi-stellar knot (less than 6" diameter) at the south edge of the halo, just 18" from the center of the main galaxy!
18" (6/21/03): fairly faint, slightly elongated, fairly small, 0.8'x0.7'. Broad, weak concentration. Five or six mag 11.5-12 stars are in the field with the closest 1.9' N. Located 25' NW of mag 7.4 SAO 7817.
