Rare 'blood moon' will be seen from Norfolk
Archant Norfolk 2018
It's a rare spectacle sure to delight sky-watchers.
The night of January 20/21 will see a so-called blood moon.
The phenomenon, which usually occurs just twice in every three years, is caused by a lunar eclipse, where the earth’s shadow prevents light from the sun from reaching our nearest celestial neighbour.
Sunlight scatters through the earth’s atmosphere as the three bodies perfectly align, making the moon appear red.
The spectacular event should be visible from Norfolk - provided the skies are clear enough to see the moon.
But the bad news for would-be lunar eclipse watchers is the timing. For the skies over our region are not expected to turn red until after 4am on the morning of Monday, January 21.
