While you may not relish the prospect of waking up in the small hours most Monday mornings, observers in the British Isles and Western Europe will want to set their alarms no later than 5am GMT on 21 January to see this month’s showstopper celestial event — a total lunar eclipse of an unusually close ‘supermoon’. The total lunar eclipse is also visible in its entirety (weather permitting) from the Americas.
Friday, 27 July sees the second total lunar eclipse of 2018, which also happens to be the longest of the 21st century. Observers in Antarctica, Australasia, Russia, Asia, Africa, Scandanavia, Europe, Central and Eastern South America will see the event. The Moon rises at mid-eclipse as seen from the British Isles, some 6 degrees north of Mars at opposition.
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.
