The asteroid was discovered on 9 March 1984, by American astronomer Brian Skiff at Lowell's Anderson Mesa Station in Flagstaff, Arizona, and named after musician George Harrison.
[1] A first precovery was taken at Palomar Observatory in 1977, extending the body's observation arc by 7 years prior to its discovery.
[8] A rotational lightcurve of Harrison was obtained from photometric observations by Czech astronomer Petr Pravec at Ondřejov Observatory in May 2015.
[a] During the following month, photometric observations at three Italian observatories gave a second lightcurve with a period of 3.956±0.001 hours and an amplitude of 0.37 in magnitude (U=2+).
[6] According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Harrison measures 10.1 and 10.7 kilometers in diameter and its surface has an albedo of 0.19 and 0.23, respectively,[4][5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 8.1 kilometers with an absolute magnitude of 12.76.
