Association Française des Observateurs d' Etoiles Variables Siège : Observatoire Astronomique de Strasbourg 11, rue de l'Université(c) 67000 Strasbourg http://cdsweb.u-strasbg.fr/afoev/ International Meeting on Variable Stars 26th, 27th and 28th of August 2002 Bourbon-Lancy (France) ===== Last Announcement ===== Dear Colleagues, We are pleased to confirm that the AFOEV International Meeting on Variable Stars will be held from Monday August 26th to Wednesday August 28th 2002 at Bourbon Lancy (France). Objective: ======== The purpose of this meeting is to bring together variable stars observers and variable stars scientists in order to discuss the reasons why observing variable stars is an efficent way to contribute to the evolution of science, to improve the way of observing, to find how the evoluting technology permits new type of observation. It also offers a unique opportunity for close interactions between observers and users of observations and a convincing way to be sure that observing is more than ever necessary in the beginning of the 21st century. Scientific topics: ================= 1. Visual observation, its advantages, its limits ; 2. Observation with a CCD camera : photometry with coloured filters, "continuous " monitoring of stars with a small period and a small variation ; 3. The programs ; 4. The sequences ; 5. Inter associations cooperation ; 6. Beginners corner ; 7. Photographic photometry ; 8. Reduction of observations ; 9. Data processing with observation results ; 10. Publishing of observations ; 11. Variable stars and the WEB.
