In March 2018, a rotational lightcurve of Kunigunde was obtained from photometric observations by French amateur astronomer René Roy.
Lightcurve analysis gave a well-defined rotation period of 9.3650±0.0006 hours with a brightness variation of 0.34±0.01 magnitude (U=3).
Richard Ditteon at the Oakley Southern Sky Observatory (E09) determined a period of 8.82±0.02 with an amplitude of 0.30±0.05 magnitude (U=2).
Photometry by Angeli and Guimarães at observatories in Brazil and Argentina gave a similar period of 8.80 hours (U=2).
In 2013, an international study modeled a lightcurve with a sidereal period of 8.82653 hours and found two spin axes at (47.0°, 57.0°) and (234.0°, 50.0°) in ecliptic coordinates (λ, β) (U=n.a.).
