The determination of
the primary energy of extensive air showers using the fluorescence
techniquerequires an estimation of the energy carried away by
particles that do not deposit all of their energy in theatmosphere.
This estimation is typically made using Monte Carlo simulations and
thus depends on the assumedprimary particle composition and model
predictions for neutrino and muon production. In this contribution
weintroduce a new method to obtain the invisible energy directly from
events measured simultaneously with thefluorescence and the surface
detectors of the Pierre Auger Observatory. The robustness of the
method, which isbased on the correlation of the invisible energy with
the muon number at ground, is demonstrated by applying itto different
sets of Monte Carlo events. An event-by-event estimate of the
invisible energy is given for the hybriddata set used for the energy
calibration of the surface detector of the Pierre Auger Observatory.
