  It is anticipated that future space-born missions, such as Gaia, will be able
to determine in optical domain positions of more than 100,000 bright quasars
with sub-mas accuracies that are comparable to very long baseline
interferometry (VLBI) accuracies. Comparisons of coordinate systems from
space-born missions and from VLBI will be very important, first for
investigation of possible systematic errors, second for investigation of
possible shift between centroids of radio and optical emissions in active
galaxy nuclea. In order to make such a comparison more robust, a program of
densification of the grid of radio sources detectable with both VLBI and Gaia
was launched in 2006. In the second observing campaign a set of 290 objects
from the list of 398 compact extragalactic radio sources with declinations
greater -10 deg was observed with the VLBA+EVN in 2010-2011 with the primary
goal of producing their images with milliarcsecond resolution. These sources
are brighter than 18 magnitude at V band. In this paper coordinates of observed
sources have been derived with milliarcsecond accuracies from analysis of these
VLBI observations following the method of absolute astrometry and their images
were produced. The catalogue of positions of 295 target sources and estimates
of their correlated flux densities at 2.2 and 8.4 GHz is presented. The
accuracies of source coordinates are in a range of 2 to 200 mas, with the
median 3.2 mas.
