The Graphic Almanac in COELIX
||London (Great Britain)

The Graphic Almanac gives information on the major astronomical events of a full year, observable at the current observation station. You can consult it for the times of risings, meridian transits and settings of the Sun, Moon and planets. The meridian transit of a celestial body is the time when this body crosses the celestial meridian and when this body is at its highest point in the sky (thus best placed for observation). The horizontal axis of the graph corresponds to the hours of the night, from 15h to 9h the next morning. The vertical axis corresponds to the days of the year.
You can also use the almanac for a host of other phenomena such as conjunctions and encounters of celestial bodies in the sky, greatest elongations of Venus and Mercury, times when the Moon is above horizon, major meteor showers, values of the equation of time, sidereal time and julian day.
To the roght of the graph, the list of the major phenomena of the year indicates the times of the phases, apogees and perigees of the Moon, equinoxes and solstices, oppositions, conjunctions and greatest elongations of the planets, eclipses of the Moon, encounters of celestial bodies in the sky, etc.
The appearance of the graphic almanac changes dramatically when you change the latitude of the observing site, as shown on the images above. If you want accurate information, the Graphic Almanac should be calculated for a geographic location as close as possible to the user's observation station. By default, COELIX generates the almanac of the current observation station chosen by the user in the software.
