A catalogue of eclipsing variables
A new catalogue of 6330 eclipsing variable stars is presented. Thecatalogue was developed from the General Catalogue of Variable Stars(GCVS) and its textual remarks by including recently publishedinformation about classification of 843 systems and making correspondingcorrections of GCVS data. The catalogue1 represents thelargest list of eclipsing binaries classified from observations.

OT And - a Long Period EA Binary with Increasing O-C
Results are compared with Crawford, R.C. et al., IBVS 2624 (1984). Thereseems to be indication for increasing O-C. Further observations areencouraged to improve the current elements.

Radial velocities. Measurements of 2800 B2-F5 stars for HIPPARCOS
Radial velocities have been determined for a sample of 2930 B2-F5 stars,95% observed by the Hipparcos satellite in the north hemisphere and 80%without reliable radial velocity up to now. Observations were obtainedat the Observatoire de Haute Provence with a dispersion of 80Ä,mm(-1) with the aim of studying stellar and galactic dynamics.Radial velocities have been measured by correlation with templates ofthe same spectral class. The mean obtained precision is 3.0 km s(-1)with three observations. A new MK spectral classification is estimatedfor all stars. Based on observations made at the Haute ProvenceObservatory, France and on data from The Hipparcos Catalogue, ESA.Tables 4, 5 and 6 are only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr or viahttp://cdsweb.u-strasbg.fr/Abstract.htm

APT's - Automatic photoelectric telescopes
In an automatic photoelectric telescope (APT), the photometricinstrument with which measurements are made also undertakes theidentification and centering of the stars to be observed. Amicrocomputer operates both the photometer and telescope, and inaddition decides the time and order of observations. APTs are noted toexcell in the detection of variable stars with properties, such as longperiods, which could easily be missed during the shorter observationruns to which human astronomers are accustomed. A detailed account isgiven of an APT's typical operating cycle.
