John Herschel discovered NGC 5619 = h1806 on 10 Apr 1828 and recorded "vF, R; vgbM; 25"." He missed the two nearby companions, including IC 4424. Auguste Voigt independently found the galaxy again in 1865, though the rediscovery was not published.

400/500mm - 17.5" (6/8/91): fairly faint, fairly small, elongated 2:1 SSW-NNE, bright core, faint stellar nucleus. A mag 13.5 star is 1.7' NW of center. Brightest of three with IC 4424 3.5' NE and UGC 9258 3' ESE. The three galaxies form a rough equilateral triangle with sides of length 3'.

600/800mm - 24" (5/11/13): moderately to fairly bright, very elongated 5:2 N-S, ~1.6'x0.7', sharply concentrated with a very bright, very small core. Brightest and largest in a trio with IC 4424 3.7' ENE and UGC 9258 = NGC 5619C 3.2' ESE. IC 4424 appeared fairly faint, fairly small, elongated 3:2 NW-SE, ~24"x14". A mag 16 star is just off the south side, 15" from center. UGC 9258 appeared faint to fairly faint, low surface brightness (face-on spiral?), round, diffuse glow, very weak concentration, 24" diameter.
