Alqueva´s Dark Sky Reserve | Atmospheric & Optical phenomena | By Year: 2017 | Earthshines & Crescent Moons | Mértola & Mina São Domingos | Moonlight Scenes | Twilight Dawn & Dusk
Captured one day after the new moon during the Christmas week, the moon was only 2% illuminated by the sunlight. Though, we can clearly distinguish the entire disk due to a phenomenon called Lunar Earthshine. In the foreground, located in a top hill, is a beautiful well-preserved medieval castle from Mértola village, in Dark Sky® Alqueva Reserve, decorated with Christmas lights around the walls and by coincidence very well aligned with the crescent moon, forming the perfect frame for a Christmas Card.
PT: Captada no dia após a lua nova e durante a semana que antecede o Natal, a lua encontrava-se 2% iluminada pela luz solar directa. No entanto, é possível distinguir claramente todo o disco devido a um fenómeno chamado Lunar Earthshine. Em primeiro plano, localizado numa colina superior, encontra-se o bem preservado e belo castelo da vila de Mértola, na Reserva Dark Sky® Alqueva, decorado com luzes de Natal ao redor das paredes e por coincidência muito bem alinhado com a lua crescente, forma o par perfeito para um Postal de Natal.
