LEP beam energy calibration in 1995

A three point energy scan was performed in 1995 to improve the errors on the Z width and to confirm the results of the 1993 scan. For the first time since LEP was commissioned the bending field has been monitored with probes installed inside tunnel dipole magnets. Short term fluctuations, sudden jumps and typical rises in the magnetic field corresponding to several MeV per beam during a fill have been observed. Operating LEP in 1995 with bunch trains implied a shift of the center of mass energies in the case of beams colliding with an collision offset. This contribution reports the present status of the knowledge of these new effects.
