Abstract
A. Shearer, M. Redfern, T. Rowold, P. OKane, R. Butler, and C. OByrne, University College, Galway; and H. Pedersen, Copenhagen University Observatory, communicate: We have observed the position of the optical pulsar 0540-693 (Middleditch and Pennypacker 1985, Nature, 313, 659) using the European Southern Observatorys New Technology Telescope (+ UCG DIAS ESO MAMA image sharpening camera, TRIFFID) on 1993 Jan. 15-16. On each night, the 19.838-Hz barycentric power spectrum component (computed from the pulsar period given in Manchester et al. (1993, Ap.J. 403, L103) showed a single spatial peak, consistent in height with Middleditch and Pennypacker, in the center of the nebulosity and coincident with the northern maximum of Caraveo et al. (1992, Ap.J. 395, L103).
