Nubes noctilucientes
Contenido principal del artículo
Resumen
Las nubes noctilucientes (abreviatura: NNL) son nubes situadas alto en la atmosfera y vistas contra el fondo de un cielo obscuro al ser iluminadas aun por la luz solar, cuando el sol esta abajo del horizonte, en ángulos de depresión entre 6° y casi 18° (Fig. 1). Generalmente parecen cirrus o cirrostratus y con frecuencia tienen delicada configuración de filigrana, con marcada estructura ondulada. Son muy delgadas y las estrellas cintilan a través de ellas casi sin obscurecerse.
