Status report of the project 'EVN observations of radio sources used for 
geodetic EUROPE experiments'
 
                   ABSTRACT
 
 
Most of the quasars or BL Lac objects regularly observed during geodetic
VLBI experiments
show extended spatial structures at the milliarcsecond scale. For high
precision geodetic
VLBI analysis source structure effects have to be accounted for. The
proper correction of
source structure effects is possible when brightness distributions of
sources are available.
This paper presents a project to obtain high resolution images of radio
sources observed
during EUROPE VLBI experiments. The present status of the work is given.
The contribution
of the stations of the observation network is outlined.
