The OSSE detector on boar dthe Compton Gamma Ray Observatory observed the Vela Pulsar (PSR 0833‐45) during August–September 1991 and April–May 1992. Pulsed emission was detected at the 4‐5 σ level in the 0.06–0.57 MeV band in the sum of the two observing periods, as well as in each individual observation at lower significance. There is no significant variability observed. Light curves have a peak structure similar to that observed at higher energies. The spectrum is hard at lower energies and appears to require a break in the 0.5–2 MeV regions.
