Abstract: Astrometric photographic positions of the Saturnian satellite Helene obtained from 22 plates taken in 6 nights are presented. The observations are distributed between 5 missions in 1985 and 1987. All positions are compared with those calculated by \cite[Jacobson (1999).]{J99} The residuals have mean and standard deviation smaller than 0farcs25 and 0farcs30 respectively. Based on observations made at Laboratório Nacional de Astrofísica/CNPq/MCT-Itajubá-Brazil. Table 1 is also available in electronic form at the CDS via anonymous ftp to ( or via
