Observation history
NGC 5523 was discovered by William Herschel on 19 May 1784 using 18.7-inch f/13 speculum telescope.[5][6] It was described as "faint, pretty large, pretty much extended 90°, 10th magnitude star to northwest".[5]
General
The galaxy was originally thought to be isolated due to its lack of interaction with other galaxies in the past 1 to 3 billion years. However, a 2016 study reported that some irregularities of the contour of the discs and nucleated bulge at the center of the galaxy suggested that the galaxy previously had soft collisions with other galaxies.[3]
