A preliminary determination of the proper motion and parallax of the Vela pulsar was made using phase-referencing VLBI. The measured proper motion in right ascension and declination are respectively, µα
= −49.8 ± 0.2 mas yr−1 and µδ
= 30.5 ± 0.1 mas yr−1. The parallax of Vela was calculated to be π
veia = 3.16 ± 0.33 mas, which corresponds to a distance of
pc.
