ASASSN-21uy: new SU UMa-type dwarf nova Berto Monard has reported observations. Humps with a period of 0.0613(5) and a mean amplitude of 0.09 mag were recorded. Although the profile was doubly humped, the overall feature did not resemble that of early superhumps. The superhumps may be in the growing phase. Further observations are needed to see whether these humps are ordinary superhumps in the growing stage or early superhumps.
