Dust coma of 67P shortly before perihelion. Image acquired on 18 Feb. 2009, at heliocentric distance of 1.25 AU. Orientation: north is up and east is left. Field of view: 106 × 106 arcsec = 128 600 km at the comet. We highlight here the location of the dust coma structures. From left to right: adaptive Laplace-filtered image, adaptive Laplace-filtered image with the structure geometry indicated by dashed lines, Larson-Sekanina-filtered image. The dotted line traces the orbital plane of the comet.
