We present observations of Saturnian inner satellites, Janus, Epimetheus, Pandora and the new objects 1995S5 and 1995S6. Data were obtained with the COME-ON+ adaptive optics system mounted on the 3.6-m telescope of the European Southern Observatory, during the 10 August 1995 Earth crossing. During this time, the usually bright rings become faint, an ideal time to study the small inner satellites. Two unresolved objects have been detected. They have been identified with the objects 1995S5 and 1995S6, which have been detected on frames obtained with the Hubble Space Telescope, more than one day later. Astrometric reductions relative to the brighter satellites and the Cassini division yield planetocentric positions with accuracies of 015 and 026, respectively. These measurements, combined with the HST data, and the NIR photometric parameters point to the possible transient character of these objects, and provide a more accurate solution for the 1995S5 orbital parameters.
