In recent scanning tunneling microscopy experiments, confinement in an elliptical corral has been used to project the Kondo effect from one focus to the other one. I solve the Anderson model at arbitrary temperatures, for an impurity hybridized with eigenstates of an elliptical corral, each of which has a resonant level width \ensuremathδ. This width is crucial. If \ensuremathδ<20 meV, the Kondo peak disappears, while if \ensuremathδ>80 meV, the mirage disappears. For particular conditions, a stronger mirage with the impurity out of the foci is predicted.
