Vitesses radiales. Catalogue WEB: Wilson Evans Batten. Subtittle: Radial velocities: The Wilson-Evans-Batten catalogue.
We give a common version of the two catalogues of Mean Radial Velocitiesby Wilson (1963) and Evans (1978) to which we have added the catalogueof spectroscopic binary systems (Batten et al. 1989). For each star,when possible, we give: 1) an acronym to enter SIMBAD (Set ofIdentifications Measurements and Bibliography for Astronomical Data) ofthe CDS (Centre de Donnees Astronomiques de Strasbourg). 2) the numberHIC of the HIPPARCOS catalogue (Turon 1992). 3) the CCDM number(Catalogue des Composantes des etoiles Doubles et Multiples) byDommanget & Nys (1994). For the cluster stars, a precise study hasbeen done, on the identificator numbers. Numerous remarks point out theproblems we have had to deal with.

Speckle interferometry of HIPPARCOS link stars
Speckle interferometry has been carried out on 39 stars that had beenselected as provisionally suitable for linking Hipparcos positionalmeasurements to an extragalactic reference frame by Space Telescope. TheImperial College, London, speckle interferometer and the autocorrelatoron the Anglo-Australian 3.9-m telescope are used. The result is thatabout 30 percent of the stars selected turned out to be confirmed orsuspected multiple stars in the range 0.03-0.7 arcsec.

Observation of a secondary extinction during the occultation of SAO 114159 by /18/ Melpomene
A secondary occultation of the fainter component of SAO 114159 wasobserved from Fernbank Observatory on Dec. 11, 1978, at 9h 11m UT. Aninterpretation consistent with the data is that the event was caused bya satellite of (18) Melpomene with a minimum diameter of 48 km.
