Summary
DescriptionAnalemma Earth.png |
English: Analemma for planet Earth.
This is a plot of the position of the sun at 12:00 noon at the Royal Observatory, Greenwich (latitude 51.4791° north, longitude 0°) during 2006. The horizontal axis is the azimuth angle in degrees (180° is facing south). The vertical axis is the altitude in degrees above the horizon. The first day of each month is shown in black, and the solstices and equinoxes are shown in green. It can be seen that the equinoxes occur at an altitude of = 90° ∼ 51.4791° = 38.5209°, and the solstices occur at ± ε where ε is the axial tilt of the Earth, 23.439°. This plot was constructed using altitude and azimuth data generated by JPL Horizons. This data is listed below. The analemma is plotted with width highly exaggerated, which permits noticing that it is very slightly asymmetrical (due to the two-week misalignment of the apsides of the Earth's orbit and its solstices). On November 3 the equation of time can be up to 16 min 23 sec fast; on February 12 it can be up to 14 min 20 sec slow. A similar plot can be found at [1]Français : Un exemple de courbe analemme pour la planète Terre.
Chaque point de cette courbe représente une position du soleil à 12:00 (midi) vu à l'Observatoire royal de Greenwich (latitude 51.4791° nord, longitude 0°) pendant l'année 2006. L'axe horizontal représente l'azimut en degrés (180° est face au sud). L'axe vertical représente la position du soleil au-dessus de l'horizon. Le premier jour de chaque mois est affiché en noir, et les positions de solstices et équinoxes sont affichés en vert. On peut observer que les équinoxes ont lieu à l'altitude = 90° − 51.4791° = 38.5209°. Ce schéma a été construit en utilisant les données d'altitude et d'azimut fournies par le site JPL Horizons. Ces données sont listées ci-dessous. La largeur de ce diagramme a été exagérée ce qui permet de montrer une asymétrie due au défaut d'alignement des apsides de l'orbite terrestre et des solstices. Le 3 Novembre cette courbe montre une avance de 16 min 23 sec; le 12 Février elle montre un retard de 14 min 20 sec. Un diagramme similaire peut être trouvé sur le site [2]. |
