Abstract:
Puck, a faint satellite very close to Uranus' planet, was discovered
by Voyager 2 Spacecraft images in 1986. Ever since then, few
observations from Earth have been made. This prompted us to start a
program of systematic observations of this satellite with the 1.6m
telescope at the Laboratorio Nacional de Astrofisica/MCT (Itajuba,
Brazil). The success of the observations is mainly due to the use of a
Coronagraph developed at Observatorio Nacional/MCT (Rio de Janeiro,
Brazil). This article presents astrometric positions obtained from
Earth observations of Puck and of the five major Uranian satellites
for four nights in 2004. Those positions are compared to the
theoretically calculated positions from JPL Development Ephemeris. For
Puck, the root mean square (rms) of the mean residual was found to be
84 milliarcseconds (mas). The stars' USNO-A2.0 catalog (I/252) was
used as a reference system for the astrometric calibration.
