- 759 observations made from 1995 June 10 to 1997 June 2

Astrometric positions of Triton (N1) from 759
CCD frames taken at the oppositions of 1995 through 1997 are
presented. The images were obtained over 35 nights. Observed positions
have been compared with the calculated positions from Jacobson. The standard
deviations are of the order of 0.09 arcsec.
