                            GENERAL INFORMATION                       

    The group of European astronomers coordinated by E. OBLAK is concerned
    with the study of visual double stars with angular separations of 1 -
    15 arc seconds. The group applies CCD photometry with VRI filters to
    objects listed in the Hipparcos Catalogue. It has used observatories at
    La Silla (Chile) (under an ESO project ending in 1994), La Palma and
    Calar Alto (Spain), Haute-Provence (France), Suhora (Poland), Hoher
    List (Germany) and Chiang Ma (Thailand), and also Chinese
    observatories.
    
    As a side-project in collaboration with the Strasbourg Star Data Centre
    and Dr. P. Couteau of the Nice Observatory (future collaboration with
    the Toulouse Observatory is also expected), a photometric data base for
    star systems is being compiled at the Besancson Observatory, and will
    later be generalized to include all categories of systems.
    
    The ultimate objective of these projects is to investigate the
    formation and evolution of stars in relationship to galaxy structure.

    =================================================================

    J. A. Docobo's  research group is engaged in a three-year (1993-1995)
    programme involving micrometer measurements of visual double stars at
    Pic du Midi and Nice (France), Calar Alto and Fabra (Spain) and Merida
    (Venezuela), as well as CCD measurements of wide binaries at Merida
    (Venezuela) and Yebes (Spain).

    P. Baize asks for  the  following  errata  in  previous  Circulars 
    to be noted.

         Circular No. 119: In the orbit of McAl 33, w should be 
             158.0 deg, not 113.0

         Circular No. 120: ADS 9547 is Ho 60 not Ho 50

                                IN MEMORIAM                           

    As many of you will know, Dr. Sylvain AREND, one of Europe's most noted
    astronomers, died on February 18th 1992. Dr. J. Dommanget of the
    Belgian Royal Observatory has requested that this sad occurrence be
    noted in the Information Circular.
    
    Born in Robelmont, Luxemburg, in 1902, Sylvain Arend studied at the
    Free University, Brussels, where he obtained his doctorate in Physical
    Sciences and Mathematics with the highest honours. In 1928 he obtained
    a grant to work as an assistant at the Belgian Royal Observatory, with
    which he continued to be associated until his retirement in 1967 as
    Head of the Department of Astrometry and Celestial Mechanics.
    
    Arend's main interests were astrometry and astrometric photography.
    The fruits of his extensive work in this field, summarized in his 80 or
    so papers, included the discovery of a nova (1952 Scuti), three comets
    (one of them the well-known Arend-Roland comet), numerous variable
    stars and fifty or so asteorids, as well as observations of the
    positions of literally thousands of other asteroids. Of particular
    relevance to IAU Commission 26, he was also responsible for putting new
    life into work on double stars at the Royal Observatory; following
    contacts with USA specialists during visits to the Yerkes, Mt. Wilson
    and McDonald observatories, he set up the Royal Observatory's 45 cm
    equatorial telescope, and went on to devise a new method for
    calculation of double star orbits.

                   NOTES ON PREVIOUSLY LISTED PAPERS                  


No. 13) Dr W. I. Hartkopf has detected two errata in Table 3 of his 
    paper "ICCD Speckle observations of binary stars XI. Measurements 
    during 1991-1993 from the Kitt Peak 4 m telescope".  Astron. J. 
    108(6), 2299 (1994). 

     i) The residue of theta with respect to Docobo and Costa's  
        orbit for WDS 00550 N 2338 (STF 73 AB) is -0.3 deg, not  
        +6.2 as published.

    ii) The orbit for COU 606 should be referenced "Ling 92", not 
        "D&L 92" as published.

No. 21) Dr J. A. Docobo notes that Section 3 of the paper "A
    trial-and-error approach to the determination of the orbital parameters
    of visual binaries" (Pourbaix, D. Astron.  Astrophys. 290, 682 (1994)),
    comments on his orbit calculation method in a way that may be
    misleading. This method does not optimize directly over the manifold of
    all the posible orbits that can be calculated from all the available
    observations, and it does not use Cid's (1958) method to calculate any
    orbit. Rather, it relies on the professional astronomer's experience to
    identify three reliable observations, generates the submanifold
    consisting of all possible orbits through these three points (not by
    Cid's method), and uses a subset of the remaining observations to
    optimize on this submanifold (again the astronomer's experience is
    appealed to for definition of a suitable subset).

                     PAUL BAIZE NOUS A QUITTES

Depuis la mort de sa seconde femme en juin dernier, nous redoutions le
pire pour le docteur Baize, age et affaibli. Helas la nouvelle de son
deces nous est arrivee le 10 octobre.

Paul Baize est ne a Paris en 1901 d'une famille normande. Son pere,
medecin, exige de son fils qu'il se consacre, lui aussi, a la carriere
medicale. De fait, Paul devient un brillant pediatre, au cabinet
celebre, il est aussi professeur a l'Hopital des Enfants Malades a
Paris et auteur de nombreuses communications medicales. Mais la passion
de l'astronomie se fait jour tres tot et il meme parallelement une
carriere d'astronome tout aussi devorante.

Membre de bonne heure de la Societe Astronomique de France, il acquiert
a 20 ans une lunette de 108 mm et observe les etoiles doubles. Ses
premiers resultats paraissent dans le grand catalogue d'Aitken. Puis
des 1930, on lui confie les lunettes de l'Observatoire de Paris,
d'abord la 305 mm, puis la 380 a partir de 1947. Son activite
d'observateur ne cesse qu'a sa retraite et son retour en Normandie en
1971, apres 25.000 mesures de tres haute qualite. C'est lui, le
premier, qui a montre les enormes possibilites des lunettes de moyenne
puissance.  L'activite du Dr. Baize ne se limite pas a l'observation,
il publie plus de cent cinquante memoires et articles, tous sur les
etoiles doubles. Il determine plus de deux cents orbites et est
l'auteur d'une methode de calcul des parallaxes dynamiques tres utilise
jusqu'a nos jours.

Il n'a cesse de travailler qu'a la mort de son epouse, il n'a pas
supporte ce nouveau deuil.  Officier de la Legion d'Honneur, Commandeur
de l'Ordre du Merite, titulaire de la medaille americaine de la
meilleure contribution amateur (1989), il est un des douze medailles du
centenaire de la Societe Astronomique de France en 1987.

                    IN MEMORIAM, DR. PAUL BAIZE 

It is with great sorrow that we learn of the recent death of Dr. Paul
Baize.

Dr. Baize was one of this century's most active and esteemed
astronomers, and one of those who have most contributed to the IAU
Commission 26 Information Circular, having used this platform on 68
occasions to announce a total of 471 binary star orbits. His first
communication in the Circular appeared in its first issue (February
1954), his last in Circular No. 121 (October 1993).  Only in 1994, at
94 years of age, did he finally decide to calculate no more orbits, a
decision he informed us of in a touching letter he sent us in July of
that year.

Our hearts go out to his family, who can take solace in the certainty
that his life and scientific achievements constitute an example and a
touchstone for those he leaves behind and for future generations.

Rest in peace.

                    ERRATUM OF THE AUTHORS

Dr. Pavlovic noted in Circular No. 126 the following errata:  In the
orbit of ADS 5400, omega should be 244.8 degrees, not 296.6 degrees,
and Omega (2000) should be 90.0 degrees, not 141.8 degrees.
