This paper presents the results of observations
of the inner Jovian satellites Thebe, Amalthea, Adrastea and Metis made
in October–November 1999 and in November 2000. We provide and
of Thebe and Amalthea with respect to the Galilean
satellites, while the positions of Adrastea and Metis are referred
to either the Galilean moons or to Thebe or to Amalthea.
All observed positions are compared with theoretical ones.
Residual statistics show an inner accuracy of our observations in the range
from about 0.1 to 0.9 arcsec. The dependence of the differences
of the observed and calculated positions on the orbital longitude
is presented for our observations of Adrastea and Metis.
Key words: planets and satellites: individual: Jovian inner satellites / astrometry
