A high-cadence TNO light curve

The Classical and Large-A distant Solar SYstem Survey (CLASSY) is a deep TransNeptunian Object (TNO) search using the MegaPrime camera on the Canada-France-Hawaii Telescope. During one of its observing runs in the summer of 2022, a fortuitous confluence of circumstances resulted in one of the search fields receiving nine nearly consecutive nights of data sets, each containing 3-4 hours of imaging data of 5-minute exposures. This unusually dense cadence provides an excellent data set to look for variability in the outer Solar System objects that happen to be in the field. In this poster, we report the results of an examination of the brightest TNO in the field (the previously known TNO 2001 OK108 with no published light-curve study) and have measured its photometric time series to determine if any rotational periodicity is detectable for this TNO. As of the time of writing, we have a possible detection of a period with a ‘normal’ TNO rotational period and amplitude, with detailed information to follow.
