Abstract
MIOSOTYS (Multi-object Instrument for Occultation in the SOlar system and TransitorY Systems) is a multiple-object, high-speed photometer primarily designed for the observation of serendipitous stellar occultations by small (less than or of the order of 1 km at 40 AU) transneptunian objects as well as other high time resolution astronomical subjects. It is currently a visiting instrument to the 1.93m telescope at Observatoire de Haute-Provence (OHP), France. In this paper, we give a brief introduction to the TNO target select strategy and present the preliminary result of the first scientific observation in February 2010.
