Measurement of triple gauge boson couplings                                    
from W-pair production at LEP energies up to 202 GeV.                          
  
        A measurement of triple gauge boson couplings is presented,            
        based on W-pair data recorded by the OPAL detector at LEP during       
        1999 at cenntre-of-mass energies of 192-202 GeV with an integrated     
        luminosity of 220 inverse picobarns. These results are combined        
        with our previous measurements at centre-of-mass energies of           
        161-189 GeV and with results from the single W and single photon       
        processes.
