摘要：
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 Jacobson (1999). The residuals have mean and standard deviation smaller than 0 ".25 and 0 ".30 respectively.
