We used the USNO A2 catalogue of stars for the astrometric reduction. With the help of observations of optical counterparts of ICRF sources, a zonal correction to the USNO A2.0 catalogue was computed and applied to the Phoebe positions. Topocentric ICRF J2000 Phoebe positions reduced from CCD observations realised with the 1.2m of the OHP Observatory. The positions proposed in the following table is corrected from a systematic effect introduced by the USNO A2.0 reference stars. This correction was estimated after ICRF optical counterparts observations (Fienga and Andrei, 2002, A&A, submitted) Some observations published by Fienga et al. were excluded since they were later refined and republished in Gomes-Junior A.
