Astrometry of Pluto from 1969 to 1989
One hundred seventy-five accurate positions of Pluto obtained during 20 years of observations at the Asiago Astrophysical Observatory are compared with the JPL Development Ephemeris DE202. The residuals plotted versus epoch show a systematic trend, with an amplitude up to 1".5 in RA. The run-of...

Summary: | One hundred seventy-five accurate positions of Pluto obtained during 20 years of observations at the Asiago Astrophysical Observatory are compared with the JPL Development Ephemeris DE202. The residuals plotted versus epoch show a systematic trend, with an amplitude up to 1".5 in RA. The run-off in RA found by other authors is confirmed. Twenty-nine previously unpublished positions, measured mainly on plates obtained at ESO-La Silla in the years 1988-1989, are also reported. |
