[3] Alsatia is a non-family asteroid of the main belt's background population when applying the Hierarchical Clustering Method to its proper orbital elements.
[1] Several rotational lightcurves of Alsatia have been obtained from photometric observations by Robert Stephens (2000),[12] Laurent Bernasconi (2005),[13] astronomer at the Oakley Southern Sky Observatory (2011),[15] Brian Warner (2011),[16] and Daniel Klinglesmith (2017).
[14] Lightcurve analysis gave a consolidated rotation period of 9.614 hours with a brightness amplitude of 0.17 to 0.29 magnitude (U=2/2/2/3/3-).
[6][7][8][9][10][11] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0415 and a diameter of 63.75 kilometers based on an absolute magnitude of 10.05.
[5][10] This minor planet was named after the French province Alsace (regained from Germany after the WWI) in northeast France between the Rhine river and the Vosges mountains.
