Here is some general information useful for proposal preparation, on visibility and predicted brightness of 67P etc.
  • Finder charts (5'x5', DSS R) showing the comet's path are available here (for 2014 visibility from ESO, but more generally useful).
  • Visibility plots for 3 observatories (ESO Paranal, Mauna Kea, La Palma) showing nightly visibilities for 2014-2016 are attached to the end of this page.
  • More general visibility plot showing elongation, declination etc 2014-2016:
  • Expected brightness (R-band, i.e. dust coma) from Snodgrass et al 2013:

    Magnitude within aperture of radius 10,000 km at the distance of the comet. Mission milestones in 2014 are marked: (a) Switch on of the spacecraft (January 20th, 2014); (b) Expected beginning of detectable activity, at 4.3 AU (March 2014); (c) The nucleus begins to be resolved by the OSIRIS Narrow Angle Camera on Rosetta (July 2014); (d) Orbit insertion (August 2014, at 3.5 AU); (e) Lander released (November 2014, at 3 AU).

  • Expected brightness (following same approach) for a 1 arcsecond radius aperture, as an approximation of the point-source magnitude to be expected:
  • Alternative format of visibility plot (for 2014):

  • And showing 2012-2015:
