PREFACE
The IAU Symposium No. 61, New Problems in Astrometry, was held in Perth,
Western Australia, from 13th to 17th August 1973, under the sponsorship of Com
mission 8 (Positional Astronomy), 24 (Photographic Astrometry), 33 (Structure and
Dynamics of the Galactic System) and 40 (Radio Astronomy). Considerable financial
support was given by the Government of Western Australia. The scientific organising
committee included Prof. Walter Fricke (Chairman), Prof. S. Vasilevskis (Vice
Chairman), Dr W. Gliese and Mr C. A. Murray (Secretaries), Dr B. G. Clark, Mr
B. Elsmore, Prof. S. W. McCuskey, Dr J. L. Schombert, Prof. R. H. Stoy, Dr K. Aa.
Strand, Dr G. van Herk, Mr H. W. Wood and Prof. M. S. Zverev. The local orga
nising committee included Mr B. J. Harris (Chairman), Mr P. V. Birch, Mr M. P.
Candy, Mr D. N. Harwood, Dr I. Nikoloff and Dr S. E. Williams. The duties of
chairmen of the sessions were performed by: B. L. Klock, W. Fricke, H. W. Wood,
C. A. Anguita, C. M. Wade, B. Elsmore, B. J. Harris, J. Kovalevsky, S. Vasilevskis,
G. van Herk, K. Aa. Strand and C. A. Murray.
This volume contains the texts or abstracts of papers presented at the Symposium.
These reflect not only the continuing interest in the classical methods of optical
astrometry, but also the exciting developments already achieved or to be expected
within the next few years through the new techniques of radio interferometry, the
use of large optical telescopes and space astrometry. This was in fact the first sym
posium in which both optical and radio astrometrists participated. Collaboration
between radio and optical observers, and the exploitation of these new techniques,
were urged in three general Resolutions which were adopted at the end of the Sym
posium.
Unfortunately several of those invited, including some members of the scientific
organising committee, were prevented from attending the Symposium; nevertheless
papers or abstracts which they submitted have been included in this volume. Among
these are several papers from our Russian colleagues, none of whom was able to be
present.
A special debt of gratitude is owed by all the participants to Mr Harris and his
colleagues for the efficient organisation of the Symposium, and, as Secretaries, we
are particularly grateful for the assistance given to us in recording the discussions
which appear in this volume. We also wish to acknowledge with thanks the valuable
help given by Mrs M. Laker in the preparation of the manuscripts for publication.
