William Herschel discovered NGC 5513 = H II-877 = h1759 on 20 Apr 1792 (sweep 1021) and recorded "pB, pL, iF." CH's reduction is 6' too far north, though he commented "PD perhaps inaccurate." JH made the single observation "pB; R" and measured a more accurate position.

400/500mm - 17.5" (7/17/01): moderately bright, fairly small, elongated 4:3 WNW-ESE, 1.0'x0.75'. Contains a bright, sharp 15" core, which is concentrated to a distinct stellar nucleus. Three mag 11-12 stars forming an arrowhead pointing west is close south. Brightest of trio with MCG +04-34-004 just 1.4' SW and NGC 5509 7' WSW. The MCG appeared faint, very small, round, only 12" in diameter. This is a small edge-on system, so I probably only picked up the brighter core. NGC 5513 is located 1.4 degrees NNW of Arcturus.
