  We report on the results of nearly 10 hours of integration of the dust trail
and neckline of comet 67P/Churyumov-Gerasimenko (67P henceforth) using the Wide
Field Imager at the ESO/MPG 2.2m telescope in La Silla. The data was obtained
in April 2004 when the comet was at a heliocentric distance of 4.7 AU outbound.
67P is the target of the Rosetta spacecraft of the European Space Agency.
Studying the trail and neckline can contribute to the quantification of
mm-sized dust grains released by the comet. We describe the data reduction and
derive lower limits for the surface brightness. In the processed image, the
angular separation of trail and neckline is resolved. We do not detect a coma
of small, recently emitted grains.
