![]() ![]() Assemelhando-se ao halo de um santo icônico, a Glória acontece em raras ocasiões, quando o luar interage com as minúsculas gotículas de água que compõem a neblina ou as nuvens. PT: Destacada como OPOD – Optics Picture of the Day, a imagem revela uma paisagem estrelada a partir do miradouro do Ujo e com vista para o extenso Vale do Tua e a sua actual albufeira visível em uma noite de neblina iluminada pelo luar, enquanto a lua minguante se deitava atrás das montanhas, criando um efeito de Glória Lunar e uma sombra do Espectro de Brocken, como pode ser visto na parte central inferior esquerda desta cena panorâmica. Captured from Dark Sky® Vale do Tua, recently certified as an International Starlight Tourist Destination located in the northern part of Portugal. The name derives from the Brocken, the tallest peak of the Harz mountain range in Germany. When viewed from a mountain, glories are often seen in association with a Brocken spectre, also called Mountain spectre, the apparently enormously magnified shadow, cast when the moon or sun is low, on clouds below the mountain on which the viewer is standing. Since this point is by definition diametrically opposed to the moon’s position in the night sky, it always lies below the observer’s horizon when the moon is up. Consisting in one or more concentric rings successively dimming, in which each is red on the outside and bluish towards the centre, it is centered on the antilunar point, coinciding with the shadow of the observer’s head. Resembling an iconic saint’s halo, a Glory happens in rare occasions, when the moonlight is interacting with the tiny water droplets that compose mist or clouds. Featured as OPOD – Optics Picture of the Day, the image reveals a starry landscape scene from the viewpoint of Ujo and overlooking to the extensive Tua valley and the current reservoir on a moonlit foggy night, while the Waning Moon was laying down behind the mountains, creating a ringed Moon Glory and a Brocken Spectre shadow, as seen on lower center left of this wide panoramic scene. ![]()
