A total of ∼20 hr of data obtained over six nights reveal superhumps in the light curves, confirming the star as a member of the SU UMa class of dwarf novae. The superhumps recur with a mean period of 0.053394(7) days (76.89 minutes), which represents the shortest known superhump period in a classical...
