A rotational light curve for the Kuiper belt object 1997 CV29

We present R- and V-band rotational light curves for classical Kuiper belt object 1997 CV29. The imaging data was obtained from the Canada–France–Hawaii Telescope (CFHT) archive located at the Canadian Astronomical Data Center (CADC). The data consist of one nights observations of a series of 42, 8 minute exposures in R band followed by 33, 8 minute exposures in V band acquired on the following night. Using relative photometry we determined a highly significant variation in the brightness of 1997 CV29. Using phase-dispersion-minimization we find 8.0, 11.2, and 15.8 hrs to be the most likely, periods of rotation and we argue that the ∼16 hr period is the most likely based on our limited observing window. The phased light curve has a peak-to-peak range of Δm≳0.4±0.1 mag suggesting an axial ratio of a/b≳1.45.
