[3][15] Lorraine was discovered on 17 November 1928, by French astronomer Alexandre Schaumasse at the Nice Observatory in southeastern France.
[5] Conversely, the asteroid is also considered a core member of the Eos family (Novakovic, Knezevic and Milani).
[1] In January 2005, a rotational lightcurve of Lorraine was obtained from photometric observations by French amateur astronomer Laurent Bernasconi.
Analysis of the fragmentary lightcurve gave a longer-than-average rotation period of 32 hours with a brightness amplitude of 0.16 magnitude (U=1).
[7][8][9][10][11][12] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0457 and a diameter of 62.15 kilometers based on an absolute magnitude of 10.0.
