A 'super moon' rises over the Andes mountain range in Santiago, Chile, on Tuesday
A rare form of eclipse not seen in more than 150 years is set to light up the sky across the west coast of the US.
Americans have set their alarms for before dawn on Wednesday to catch a glimpse of the so-called "Super Blue Blood Moon", which marks the rare combination of three lunar conditions to produce a unique spectacle last seen in the country in 1866.
Like any total lunar eclipse, the moon will take the "blood" prefix by taking on a red-tinted hue, with the "blue" a result of it being the second full moon in a single month.
This eclipse also marks the point in the moon's orbit at which it is as close as it can get to the Earth, making it appear larger and brighter than usual, when it becomes a "super moon".
