Dust coma of 67P in the pre-perihelion epoch. Broadband R images acquired on 1 Jun. 2008, 8 Sep. 2008, 22 Oct. 2008 (Tozzi et al. 2011) and numerically enhanced with the adaptive Laplace filter. Field of view: 100 × 100 arcsec = 210 000 km, 160 000 km, and 135 000 km at the comet. Some features are detected in the coma, although not with every image-processing technique. The salt-and-pepper pattern represents the noise structure of the background, with embedded stars trails. The dotted line traces the orbital plane of the comet.
