Optical data taken in January 1987 from La Silla, compared to the discovery plate of 1975.2, show no proper motion for PSR 0833-45, while a very significant one was expected if the pulsar originated in the center of the Vela SNR, believed associated with it. The data yield a good estimate of the position of the parent SN event, highly asymmetric with respect to the present SNR and incompatible with all the Vela centers considered so far at various wavelengths. If the PSR/SNR association is to be kept, either an extreme asymmetry of the SNR is required, or both objects have to be much older than thought so far. Both alternatives are unattractive, thus casting doubts on the reality of this classic SNR/pulsar association. 25 references.
