See January’s totally eclipsed Blue Moon

14 January 2018 Ade Ashford

On 31 January we experience the second full Moon of the month, which by one definition makes it a Blue Moon. However, for observers in north-western North America, Oceania, East Asia or central and eastern Russia, this full Moon will have a decidedly reddish hue since it will be immersed in the Earth’s shadow during a total lunar eclipse.
