In 1974-2003 the oscillation period was 159.966 min, with the phase nearly constant over 30 years. The amplitude of radial variations of the solar radius -- at the photospheric level -- is about 2 km. The mean profiles of velocity and radius differ from harmonic ones indicating a non-linear mechanism of excitation. The nature of the oscillation is unknown.
