In a total lunar eclipse, it does not disappear completely. The sun's rays, refracted in the Earth's atmosphere, can hit and illuminate the lunar surface, which will be seen in reddish tones from Earth.
From Tenerife the phenomenon can be observed minutes before sunrise (07:40), which will create a unique image: the shadow of Teide on the atmosphere, coinciding with sunrise, will point directly to the eclipsed moon in an almost perfect alignment . This double spectacle of the sky has not been observed on the island since 2001 and, in order not to miss the opportunity, the Shelios cultural association, in the hands of the scientist of the Institute of Astrophysics (IAC) Miquel Serra-Ricart, organizes an expedition to observe the phenomenon at 3,200 meters above sea level, in the Pico Viejo viewpoint, whenever the weather conditions allow it. The IAC collaborates in the online broadcasting of the phenomenon live through the website www.eclipsesolar.es.
