It was discovered by British astronomer Philip Herbert Cowell at the Royal Greenwich Observatory on 5 October 1909.
[4] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for members of the Eunomia family of 0.21 and calculates a diameter of 10.5 kilometers with an absolute magnitude of 12.2.
[3] In April 2009, a rotational lightcurve of Lynn was obtained from photometric observations made at the Oakley Southern Sky Observatory (E09) in Australia.
Lightcurve analysis gave a well-defined rotation period of 3.8377 hours with a brightness variation of 0.60 in magnitude (U=3).
[5] This minor planet is named for William Thynne Lynn (1835–1911), who worked for many years as an assistant at the Royal Greenwich Observatory during the second half of the 19th century.
