Using a simple nonlinear analysis method (E. M. Blanter et al., submitted manuscript, 2001), we are able to observe in the length of day the 18.6‐year beating of the two main fortnightly lunar tides and to measure the amplitude of the smallest one with a great accuracy. We can thus estimate the associated zonal response coefficient κ for this period. We find κ = 0.311 ± 0.010.
