 Since 2001, several rotational lightcurves of "Edwin" have been obtained from photometric observations by American William Koff at the Antelope Hills Observatory in Colorado, Richard Ditteon at the Oakley Observatory in Indiana, and French amateur astronomers Pierre Antonini, René Roy and Stéphane Charbonnel.Analysis of the best-rated lightcurve by Pierre Antonini from November 2006, gave a rotation period of 5.2906 hours with a brightness amplitude of 0.27 magnitude ().While not being a fast rotator, it has a relatively short spin-rate for an asteroid of its size.
