Abstract

We present a principle component analysis of multicolour light variations of the He-strong magnetic chemically peculiar star HD 37776 and its (O-C) diagram. The period increase rate found, (dP/dt) / P = 5.5 x 10^-6/year, is consistent with the conception of angular momentum loss through magnetically confined stellar wind.
