Two rotational lightcurves of Rotraut were obtained from photometric observations by Richard Ditteon at Oakley Southern Sky Observatory (E09), Australia, in February 2017, and by Tom Polakis at the Command Module Observatory (V02) in Arizona in May 2018.
Lightcurve analysis gave an identical rotation period of 14.297 hours with a brightness variation of 0.25±0.05 and 0.29±0.03 magnitude, respectively (U=3−/3−).
The result supersedes a tentative period determination of 14.586±0.003 hours and an amplitude of 0.24±0.01 magnitude by French amateur astronomers Stéphane Charbonnel and Claudine Rinner from July 2002 (U=2).

In 2016, a modeled lightcurve gave a sidereal period of 14.3007±0.0002 hours using data from the Uppsala Asteroid Photometric Catalogue, the Palomar Transient Factory survey, and individual observers (such as above), as well as sparse-in-time photometry from the NOFS, the Catalina Sky Survey, and the La Palma surveys (950).
The study also determined two spin axes of (201.0°, −41.0°) and (2.0°, −36.0°) in ecliptic coordinates (λ, β).
