Codiscovery of Saturn XIV, Calypso, in 1980 (Pascu, Seidelmann, Baum, Currie)
See summary of IAU decisions at Patras, Sky and Telescope, July 1983.
The great bulk of my observations of the satellites Mars, Jupiter,
Saturn, Uranus and Neptune made over 30 years with photographic plates,
CCDs, and the Hubble Space Telescope remain unpublished but exist in the
archives at the Jet Propulsion Lab, at Bureau des Longitudes, at the
Russian Space Agency and at several other institutions around the world.
These observations formed the greatest weight in fitting the new
theories of the satellites used for the space probe reconnaissance of
the planets in the 1970s, 1980s and 1990s.
Below is a list of some of my more important publications of the past 20 years.
It includes a few reviews.

I am now completing an astrometric, photometric and dynamical analysis
of Hubble Space Telescope of the inner satellites of Neptune.
