Scientific Rationale Asteroids and trans-Neptunian objects (TNO) are the most numerous in number class of Solar system objects which counts today for 790 thousands of bodies, and this number is constantly growing due to newly discovered ones. The near-Earth asteroids (NEA) and potentially hazardous asteroids (PHA) make sequential subclasses to the asteroid’s population. The latter objects are already the targets of space research and experiments today and are considered as the natural resources in the closest future.
The physical properties of the asteroids are highly variable that makes different the role of non-gravitational forces in their dynamics. Thus, propagation of their future trajectories even at small timescales requires consideration of their physical properties. This is especially important for predicting future close encounters of the potentially hazardous asteroids with the Earth.
Active experiments using space missions to asteroids do not belong anymore to science fiction. In 2018 the space-probe OSIRIS-REx (NASA) reached the asteroid (101955) Bennu, and the space-probe Hayabusa2 (Japanese Space Agency) rendezvoused the asteroid (162173) Ryugu.
The follow-up programs by the small ground-based telescopes can be beneficial for enlarging the number of objects characterized by space missions or large telescopes programs, calibrating the methods used. The Gaia catalog which is a joint effort of the European Space Agency space mission Gaia and the consortium of the universities provides access to 2 milliards of stars with proper motions, parallaxes, three color magnitudes beneficial for highly-accurate astrometry and photometry of asteroids. The Large Synoptic Survey Telescope (LSST) will provide 1.3 petabytes of data per year in the closest future, far more than can be reviewed by humans.
The international workshop is aimed at sharing and discussing recent scientific results and problems on dynamics and physics of asteroids, TNOs and natural satellites, data and methods used, exposing possibilities for follow up programs with the ground-based telescopes, establishing and enforcing collaboration between different research teams. Participation of amateur astronomers is welcome.
The topics of the workshop covers: Generation of waves by meteorological events and characterization of their source spectrum. Propagation of primary internal waves (acoustic-gravity waves, tides, Kelvin waves, tidal and planetary waves) from the lower atmosphere to the ionosphere-thermosphere. Secondary wave generation and wave-wave interactions of various scales. Direct effects of internal waves on the ionosphere and thermosphere and their role in thermosphere-ionosphere coupling. Linking ionospheric variability (electric fields, plasma parameters, etc.) and meteorological events on various time scales. Sun-Earth connection, space weather, and linking meteorological processes to solar driven variability.
Scientific Rationale Astrometry is one of the important tools to explore the Solar System objects and improves our knowledge of the dynamical and physical characteristics of these objects. The GAIA mission of the European Space Agency was launched in 19/12/2013 will cover a large space astrometric program that will improve our knowledge of observable universe containing huge number of astrophysical and Solar system objects (e.g. asteroids, comets, planetary satellites) by performing a systematic survey of the whole sky (V~20). For this purpose, the GAIA Follow Up Network for Solar System Objects (Gaia-FUN-SSO) has been set up in a framework of the GAIA consortium. The main purpose is to coordinate ground-based observations. This is very important because when an alert is given on a new object in the solar system, many and accurate observations are needed to determine its orbit. Orbital parameters are crucial for including a contribution to the dynamics’ of the Solar system as well as recognizing it. Improving its orbit by many observations, thus, is very important. Orbital parameters as identifying information is critical, otherwise, the object seen in a next observing session may appear a new object, despite it is not. At this workshop, a limited number (up to 12) of M.Sc, Ph.D. students and young astronomers will improve their ability and knowledge to evaluate astrometric and photometric observations of solar system objects, mostly asteroids, and determine orbital parameters and brightness’. Akdeniz Astrometry Workshop is performed in the frame of an International Joint Project (IJP) of French, Turkish, and Korean collaboration. Official language of the summer school will be in English
Scientific Rationale Astrometry from the ground and space allows us to explore the Solar System objects and improve our knowledge of the dynamical and physical characteristics of these objects. The GAIA mission of the European Space Agency which is scheduled for launch in 2013 will cover a large space astrometric program that will improve our knowledge of a huge number of astrophysical and Solar system objects (e.g. asteroids, comets, planetary satellites) by performing a systematic survey of the whole sky (V~20). Nevertheless ground-based observation by a follow-up program will be useful and will allow us to validate some difficult detection by the probe or to avoid the loss of some newly detected objects. Regarding the impressive improvement of the orbit accuracy which will be reached, a fundamental step in astrometry will be done and new challenges will arrive in this domain as well for the space observation and their interpretation as for the ground-based observation. At the present time, astrometrists work for the preparation of this important mission but we must think about a long term vision which will ensure the necessary manpower for the analysis of the huge amount of data and the future researches in the astrometry domain. Despite this enthusiastic future, astrometry is not included in curriculum of several countries, therefore students and young astronomers must be encouraged to reinforce the astrometric community active in astrometry. In this international context, a summer school could be an interesting way to foster young students and astronomers for this specialization.The summer school is performed in the frame of an International Joint Project (IJP) of French, Turkish, Russian, Ukrainian, and Chinese collaboration . In following the summer school, we also organize a workshop as a continuation of future activities established by the IJP to initiate data exploitation on astrometric observations by candidate/professional scientists.Official language of the summer school and the workshop is English.

Scientific Rationale The workshop “Astrometry now and in the future” is organized in the continuation of the “Summer School on Astrometry in Antalya” and is devoted to discussions of present and future activities in the astrometry domain from ground-based and space observations. Ground-based observations and space observations are complementary and this synergy can be very useful to explore some domains. This is the case for example for the dynamics of the Solar System Objects. The development of observing networks, the advent of next generation telescopes, and the next space missions will lead to an increase of data with valuable astrometric measurements. A long term vision which will ensure the manpower for the analysis of the huge amount of data and the future researches in the astrometry domain is necessary. Students and young astronomers must be encouraged to reinforce the astrometric community active in astrometry. In this international context, a workshop is an interesting way to foster young students and astronomers for this specialization. Given the above expectations, we organize this workshop on astrometry in Antalya to initiate this future plan and data exploitation on astrometric observations by candidate/professional scientists. The workshop consists of oral contributions (at most 20 mın. Each + 5 min. For discussion), complemented by optional posters.
