On April 15th, 2014 the moon will be eclipsed by the shadow of the earth. This marks the first of four eclipses occurring about 6 months part, called an eclipse tetrad. The last tetrad was a decade ago, and the next is not due until 2032.
The best eclipse visibility will be from North America and parts of South America. A team of GLORIA astronomers will celebrate this astronomical spectacle with a live broadcast from the city of Cusco, Peru, in the Sacred Valley of the Incas. Throughout Europe, totality will not be visible. However the Teide volcano, at 3718m altitude on the island of Tenerife, offers an intriguing observational prospect. When a total lunar eclipse occurs close to sunrise or sunset at Teide, the shadow of the volcano aligns perfectly with the eclipsed moon. This unique phenomenon will be observable during the eclipse of April 15th and will be broadcast live.
