Scientific rationale: The progress in computing results in the possibility to compute numerically the orbit of a single celestial object in almost all problems, even when there are close approaches and in other highly unstable cases. This has, however, only moved forward the frontiers of research in Dynamical Astronomy. Now the goal is to study the dynamical behavior of entire populations of celestial bodies, either real (observed) or only hypothetical (simulated). Thus the contributions need to focus their presentations both on the populations (such as asteroids, comets, meteors; dust particles and rings; swarms of planetesimals; space debris; extra solar planets; virtual objects expressing the uncertainty of orbit determination) and on the methods and theoretical tools (analytical theories; chaotic diffusion; non gravitational perturbations; family classification; population modeling and transport; symplectic integration; graphic representation of the results) which can be used for one or more population. A more extensive scientific rationale and a list of suggested topics are available on the web site.

The participants who prefer to stay in student dormitory (11-12 euro per night) are kindly requested to contact directly Local Organizing Committee. At the Student Dormitory only double rooms are available, so please indicate in the Registration Form the name of the other participant with whom you would be prepared to share the room. Please note that hotels Metropol, Slavija, Park as well as Student Dormitory are within walking distance (5-10 min) from Faculty of Civil Engineering, where the meeting is held.


Breakfast is included at the rate of your room and will be served in your hotel. An optional lunch will be organized only for participants and accompanying persons in the vicinity of the meeting venue. The price will be given in the Final Program.

Closing dinner:

Closing dinner will be held on Friday , Sept. 3. Price will be given in the Final Program. If you wish to attend please indicate this in the Registration Form.

Accompanying program:

Program will include a Belgrade Sight-seeing Tour, excursions to nearby interesting sights, excursion to the naive painters village, fashion shows, shopping tours and folklore performance. A definite schedule will be given in the Final Program. These excursions and shows are free of charge for the registered accompanying persons only.

Travel to Belgrade:

The Belgrade International Airport is located some 20 km from the City of Belgrade. There is a regular bus service from/to airport to/from the town Terminal, in front of the Hotel "Slavija". Taxis and international car rental services are available at the airport as well as in town. From the major European cities there is a daily direct rail and bus service to Belgrade.
You can also come to Belgrade by car. There is an underground parking lot near the conference venue (15 Dinars per hour).

Visa formalities:

For the citizens of practically all European countries, USA., Canada , Australia, New Zealand, most of South America countries (except Brazil) an entry visa is not required. For some Eastern European countries (Russia, Ukraine, etc.) an invitation letter might be necessary; it can be sent, upon request, by LOC. Citizens of other countries are kindly requested to contact the nearest Serbian and Montenegro Consulate in their countries for the information about visa formalities. Please consult web page http://www.mfa.gov.yu for necessary visa information.
A valid passport is in all cases required.


In Belgrade Serbian language is in official use. Both , Cyrillic and Latin alphabet are common. English, is spoken by many people on the streets and shops and it is compulsory in hotels, tourist offices and airport.


The Serbian currency is Dinar. The notes in use are 5000, 1000, 200, 100, 50, 20 and 10 and coins are 20, 10, 5, 2, and 1 Dinar and 50 paras (1/100). At the present moment the approx. rate of exchange is 68 Dinars per 1 Euro. Participants may change their convertible currencies in dinars in all hotels, banks, exchange offices , travel agencies and airport. The rates are very similar everywhere. Major international credit cards such as Visa, Master Card, and Diners Club are generally accepted by hotels, airlines, travel agencies, restaurants and many department stores and shops.


In September in Serbia and Montenegro the Central European Summer time is in use. It means GMT +2.

Weather and clothes:

The weather in September is likely to be fairly mild and warm, with perhaps very rare showers. The most suitable clothing for this time of the year would be light-weight clothes.


Numerous Belgrade locations are attractive for excursions because of their natural beauty and, in many cases of their historical and cultural importance. Among many available excursions LOC is planning to organize a half-day tour to National Park of Fruska Gora with visit to some famous monasteries and very picturesque town of Novi Sad. On Sunday, Sept. 5, a full-day excursion to South-west of Serbia with visit to some well-known monasteries is planned to be organized. Excursions are optional and their price will be given in Final Program.
Other destinations, such as Oplenac, the Iron Gates at Djerdap (Danube), naive painters village Kovacica, monument of Unknown Soldier at Avala etc. are also available.
Before and after the Colloquium 197, a visit to Montenegro and Adriatic coast is also very attractive and possible to organize.

Milutin Milankovitch Anniversary Symposium:

Please note that from August 30 to September 2, 2004 another meeting of interest will be held in Belgrade. It is the Milutin Milankovitch Anniversary Symposium: PALEOCLIMATE AND THE EARTH CLIMATE SYSTEM organized by Serbian Academy of Science and Arts. Registered participants of the IAU Colloquium 197 can follow the lectures at the Milutin Milankovitch Anniversary Symposium without paying the Symposium fee.
