Problems associated with a general scarcity of observations of the
southern sky have persisted since the present era of galactic
research began some sixty years ago. In his 1930 Halley Lecture A.
S. Eddington commented on the observational support given to J. H.
Oort's theory of galactic rotation by the stellar radial velocities
measured by Plaskett o 0 and Pearce: " . . . out of 250 stars only
4 were between 193 and 343 0 galactic longitude [=GBP1: 225 <
GBP11 < 15~; a stretch of one-third of the whole circuit was
unrepresented by a single star. This is the operation which Kapteyn
used to describe as "flying with one wing". By mathematical
dexterity the required constants of rotation have been extracted
from the lopsided data; but no mathematical dexterity can avert the
possi bility that the neglected part of the sky may spring an
unpleasant sur prise. As a spectator I watch the achievements of
our monopterous avia tors with keen enthusiasm; but I confess to a
feeling of nervousness when my turn comes to depend on this mode of
progression. " During the past few years substantial gains have
been made in securing fundamental data on the southern sky.
Interpretations based on combined southern and northern surveys are
producing a balanced descrip tion of galactic morphology. These
matters were discussed at a Workshop held at the Leiden
Observatory, August 4-6, 1982, attended by some 60 astronomers from
9 countries.
