CCD observations of Phoebe

Astromeric CCD positions of the Saturnian satellite Phoebe obtained from 60 frames taken in 10 nights are presented. The observations were distributed between 5 missions in the years 1995 to 1997. For the astrometric calibration the USNO-A2.0 Catalogue is used. All positions are compared with those calculated by Jacobson (1998a) and Bec-Borsenberger & Rocher (1982). The residuals have mean and standard deviation smaller than 0$.\!\!^{\prime\prime}$5, in the x and y directions. The distribution of residuals is suggestive of the need of an improvement for the orbit calculations.
