The results of pole and shape determination for 12 asteroids are prese
nted. They have been obtained by using the method described in Michalo
wski (1993; Icarus 106, 563-572). These parameters have been determine
d for the first time for 4 objects and they have been improved or conf
irmed for the rest. Because of the small number of lightcurves availab
le in the present study, future observations, taking into account the
results from this paper, are proposed. (C) 1996 Academic Press, Inc.
