Corwin's Notes
=====
NGC 5591 is a double interacting system with distorted arms and plumes. Swift
does not mention any irregularity in his description (copied exactly into the
NGC), so he presumably saw only the brighter object. In the past, I've
labeled the galaxies the eastern and western components of NGC 5591, but I've
changed these labels so that the fainter eastern galaxy is a companion of the
brighter western galaxy.
Also see NGC 5586 where this figures in that object's identification.
Steve's Notes
=====
NGC 5591
24" (6/15/15): at 375x; the brighter western component of this merged, interacting double system appeared fairly faint, fairly small, elongated 3:2 E-W, roughly 0.6'x0.4', brighter core, fairly low surface brightness. The attached eastern component (PGC 93125) is elongated 5:2 E-W, ~0.5'x0.2' and contains a small, slightly brighter nucleus or knot, 6"-8" in diameter. The two nuclei are 22" apart (measured on the DSS2).
17.5" (5/15/99): faint, fairly small, elongated 5:2 ~E-W, 1.2'x0.5', slightly brighter core. A mag 11 star lies 2.7' SE. NGC 5587 lies 13' NNW. Either the pair was unresolved or I only viewed the brighter western component of this disturbed double system.
