    Figura de la Luna Aparente y Libración Topocéntrica

    Los movimientos de Libración en Latitud y Longitud de la Luna, permiten en cada momento tener un aspecto diferente de la misma. Aunque existe diverso software que permite calcular estos parámetros, como se suele decir, más vale una imagen que mil palabras. En el USNO, se dispone de una herramienta que actualiza la imagen aparente de la luna, mostrando además los valores subsolar y surterrestre.




    Con la imagen tenemos la apariencia real del disco lunar visto desde la Tierra a la hora que aparece en Tiempo Universal. El norte celeste está hacia arriba y el Este hacia la izquierda.


    La imagen muetra los valores de la libración geocéntrica, eso es, vista desde el centro de la tierra, pero para obtener los valores de la libración topocéntrica, la observada desde un lugar cualquiera de la Tierra, hay que introducir una variaciones. Como no he encontrado una explicación de cómo llevar a cabo los cálculos, detallo cómo hacerlos con un sencillo algoritmo. Siendo


    H el ángulo horario de la Luna, calculado a partir de la hora siderea local y la ascensión recta de la luna.

    P el Angulo de Posición del Norte

    la latitud del observador

    la declinación geocéntrica de la Luna

    la paralaje geocéntrica la de la Luna


    Calculamos unos parámtetros auxiliares









    y obtenemos los valores de la diferencia en libración en longitud y latitud

    Mope.io was enjoyed millions of times on desktop, and is now OFFICIALLY on Android! Start as a tiny mouse, in world of dangerous animals- except, these animals are other players! Forage for food, avoid getting eaten, and progress up the food chain. Learn the abilities of each animal, and go on the HUNT. The more powerful you become, the more players you can attack! Mopeio is a ton of fun, give it a try!
