  47. The observer's latitude on Earth. Can also be set in
  48. the KOSMORRO_LATITUDE environment variable.

  50. The observer's longitude on Earth. Can also be set in
  51. the KOSMORRO_LONGITUDE environment variable.
  52. --date DATE, -d DATE The date for which the ephemerides must be calculated.
  53. Can be in the YYYY-MM-DD format or an interval in the
  54. "[+-]YyMmDd" format (with Y, M, and D numbers).
  55. Defaults to current date.
  56. --timezone TIMEZONE, -t TIMEZONE
  57. The timezone to display the hours in (e.g. 2 for UTC+2
  58. or -3 for UTC-3). Can also be set in the
  59. KOSMORRO_TIMEZONE environment variable.
  60. --no-colors Disable the colors in the console.
  61. --output OUTPUT, -o OUTPUT
  62. A file to export the output to. If not given, the
  63. standard output is used. This argument is needed for
  64. PDF format.
  65. --no-graph Do not generate a graph to represent the rise and set
  66. times in the PDF format.
  67. --debug Show debugging messages
  68. By default, only the events will be computed for today. To compute also the
  69. ephemerides, latitude and longitude arguments are needed.
