                             FIRST ANNOUNCEMENT

                      of the "Ceres 2001" Workshop on:

                   Astrometry and Physics of Minor Planets
                         from Observational Networks

  Workshop dedicated to the bicentenary of the discovery of Ceres by Piazzi
         proposed to be held on October 9-12, 2001, in Paris, France
      organized by Institut de mécanique céleste/observatoire de Paris

Sponsors:
This workshop is sponsored by CNRS (Centre National de la Recherche
Scientifique) and by Observatoire de Paris.

 Scientific program:

This workshop plans to gather professional and amateur astronomers
interested in asteroids and more generally in small bodies of the solar
system, modeling motions, studying physical properties of these objects and
observing through networks. The goal of this workshop is also to review the
techniques used at present time for the observations of asteroids. The
proposed topics
of the workshop are:

- Astrometric observations of the asteroids: towards a better accuracy.
Numerous astrometric observations of asteroids are regularly made. However,
it is necessary to increase the accuracy of these observations in order to
be able to support dynamical studies and to find out non gravitational
forces. Theoretical studies connected to observational works may also be
reviewed during the workshop. The use of new stellar catalogues together
with propositions for new standard procedures of astrometric reduction
should be discussed.


- Prediction and observation of stellar occultations by asteroids:
increasing the efficiency of the observers networks.
The observation of the stellar occultations by asteroids is one of the
powerful methods for the determination of the size and figure of asteroids.
However, very accurate predictions are needed, especially for small
asteroids in order to be able to observe the occultations. Moreover, a dense
network of observers on the predicted path of the asteroid 'shadow' is
necessary to successfully observe the events and gather valuable data.
Amateur astronomers are of great help for this purpose.

- Photometric observations of asteroids: shape and spin axis
determination.
The observation of the photometric behaviour of the asteroids allows to
determine the shape and the rotation parameters of the asteroids from the
analysis of their lightcurves. These observations will constrain, together
with the observation of occultations, the models of the figure of the
asteroids.

- Satellites of asteroids, binary asteroids: towards the detection of new
systems.
The satellites of asteroids have been suspected and already detected by
indirect observations and are now directly observed. However, very few
observations are available: more are needed in order to constrain the
formation of such systems. New methods of observations are necessary such as
adaptive optics but the astrometric accuracy remains necessary.

- Observation of other Solar System small bodies:
Comets and planetary satellites need to be observed and may be observed with
the same methods as used for the asteroids. An observational effort through
international campaigns of observations and through new dynamical models may
be encouraged to improve our
knowledge of several small non gravitational effects.

- Networks of observers: what to expect from new technologies?
The networks of observers should be encouraged and
developed by using small automatic telescopes managed by professional and
amateurs astronomers. The difficulties of some specific observations (Near
Earth Asteroids, Kuiper Belt Objects) may be pointed out and experience of
the observers should be of great help for the observers community.
Collaborations between professionals and amateurs have to be encouraged.


Contributed papers:
Oral communications will be 20 minutes long including questions. Overhead
projectors and video projectors will be available. Posters may not exceed
1meter x 1meter. The scientific organizing committee retains the right to
shift proposed oral communications into posters (and vice versa) depending
on the subject. In that case, the authors will be notified.

 Abstracts:
Note that the deadline to send the abstracts is June 1. The abstracts sent
before this deadline will be published in a book of abstracts distributed to
the participants before the workshop.

 Proceedings:
The accepted contributed papers should be published with the invited review
papers in the proceedings. Contributed papers should not exceed 4 pages. The
proceedings will be sent free of charge to the participabts of the workshop.

 Accomodations in Paris:
Hotel reservations should be made upon request with your registration form
before the deadline (please indicate the standard of the hotel that you
wish; note that the price for one night in a two-stars hotel near the site
of the workshop is around 400 FF (61 Euros). Lunches will be available in
the area of the conference and are included in the registration fee.

 Transportations:
Paris is reachable by the major airways companies. Inside Paris, travelling
by car is not easy, but public transportations are easy to use (be carefull
from the pickpockets...). With a photograph, you may get a low rate
transportation pass valid on buses, subways and trains in the Paris area
during the time of the workshop.
