In line with the concept of the galactic belt of advanced life, we eva
luate the sky distribution of detectable artificial sources, using a s
imple astrophysical model. The best region to search is the median ban
d of the Milky Way in the Vulpecula-Cygnus region, together with a nar
rower one in Carina. Although this work was done in view of a proposal
to send a SETI probe at a gravitational focus of the Sun, we recommen
d these sky regions particularly for the searches of the sky survey ty
pe.
