12.12.08: Luna en Perigeo

[MigL]

Hola.

Si no lo he mirado mal, la próxima luna llena coincidirá con el Perigeo (la luna estará en el punto más cercano a la tierra ).

Además, en CN ha comentado que será la distancia más cercana (más pequeña) de los últimos 15 años.


No dejéis de echarle un vistazo, a pesar de que sea luna llena...


Pongo unas citas:

...No dejes de probar el rojo con la luna llena o de día. Fijate en el contraste que obtienes dentro de los mares.

...durante una luna llena mirad el crater Atlas (en el cuadrante noreste) que forma un duo con Hercules muy facil de reconocer Hercules. Atlas tiene dos penachos piroclasticos negros muy marcados. No intenteis verlo con luces rasantes. Ya sabesis que en la luna hay detalles que se ven con luces rasantes (relieves) y otros que han de verse con luces altas (albedo)

Salu2, MigL

Será toda una gozada poder verla en todo su apogeo.

Apogeo no, perigeo,

Apogeo no, perigeo,

Apogeo = máximo esplendor.

[SO4H2]

Pues en Pamplona tenemos las nubes en pleno APOGEO, y esta mañana las teníamos en pleno PERIGEO (niebla).

APOTEÓSICO.

[MigL]

Pues yo por mi ventana de observación no tengo ni una sola nube...


... ahora, que la luna tampoco se asoma por aquí
