We present optical astrometry of archival ground and space based imaging of the companion to PSR J1740-5340. The optical position of the companion is significantly offset from the timing position of the pulsar. We briefly investigate the effects of this inconsistency on other timing parameters and compare our position with an improved position of PSR J1740-5340 from recent, preliminary, timing results.
Key words: stars: pulsars: individual: PSR J1740-5340 / astrometry / Galaxy: globular clusters: individual: NGC 6397
