An optical spring effect has been observed in the motion of a Fabry-Perot cavity suspended to the Low Frequency Facility (LFF). The experimental set-up consists of 1 cm long cavity hanging from a mechanical isolation system, conceived to suppress seismic noise transmission to the optical components of the VIRGO interferometer. The observed radiation pressure effect corresponds to an optical stiffness kopt ranging between 2.5 × 104 and 6.5 × 104 N/m. The measured relative displacement power spectrum is compatible with a system at thermal equilibrium within its environmental. The absorption coefficient γl = 5.8 1/ s, associated to the longitudinal motion of AX, is found by fitting the data selected around the optical spring resonance 65 - 80 Hz. The upper limits of 10-15 m/√ {Hz} at 10 Hz for seismic and thermal noise contamination of the Virgo test masses, suspended by a SuperAttenuator, are deduced by the data.
