BVRI photometric observations and light-curve analysis of GEO objects

BVRI photometric observations of Geosynchronous Earth Orbit (GEO) objects were conducted with the 1.5 m Cassini Telescope located in Loiano, Italy. The observatory is operated by the INAF (National Institute for Astrophysics) Astronomical Observatory of Bologna, Italy. The Ritchey–Chre´tien optical system is equipped with the BFOSC (Bologna Faint Object Spectrograph and Camera), a multipurpose instrument for imaging and spectroscopy, with an EEV CCD (13401300 pixel). This paper deals with the results of the photometric observations of several targets from the SSN (Space Surveillance Network) catalog that were acquired in May and December 2013
