The unusual multiwavelength lightcurves of GRB 101225A are revisited by assuming that it is from an off-axis GRB powered by a newborn magnetar. We show that its optical afterglow lightcurve is fitted with the forward shock model by parameterizing its jet structure as a Gaussian function with a half opening angle of the jet core as 1.67. The derived initial Lorentz factor (Γ0) is 120, and the viewing angle to the jet axis is θv = 3.7 . Tentative QPO signatures of P = 488 seconds and P = 250…
