Americans will be treated to a rare celestial event on Wednesday (January 31), when a blue supermoon is turned red during a total lunar eclipse.
The phenomenon, which last occurred in the US in 1866, concludes a series of recent supermoons, dubbed the ‘Supermoon Trilogy’ by NASA.
The space agency has said that the moon will orbit 223,068 miles from Earth, rather than the usual 238,855 miles, causing it to appear up to 14 percent bigger in the night sky.
Wednesday will also see a blue moon, which occurs whenever two full moons rise in the same calendar month.
If that wasn’t enough, there will be a spectacular total lunar eclipse. Also known as a blood moon, the eclipse will make the moon glow an orangey red.
What time is the eclipse 2018 in the USA?
Skywatchers on the US’s west coast will have the best views of the eclipse, with NASA confirming that residents of Hawaii, Alaska and California all the way up to western Canada should be able to see the entire display, weather permitting.
The super blue moon eclipse will enter its umbral stage at 3.48am PT – where the moon starts moving into the Earth’s shadow – and reach totality at 4.51am.
Totality will last a full 1 hour and 14 minutes, ending at 6.05am, leaving plenty of time to take in the breathtaking views.
Viewing conditions will not be as favourable for those on the eastern coast, because totality takes place so close to sunrise.
Gordon Johnston, NASA program executive and lunar blogger, said: “Unfortunately, eclipse viewing will be more challenging in the eastern time zone.
“The eclipse begins at 5.51am ET, as the Moon is about to set in the western sky, and the sky is getting lighter in the east.”
New Yorkers and anyone living on the Atlantic coast are advised to wake early and travel to a high-up location away from any manmade light pollution to get the best views.
Mr Johnston added: “Your best opportunity if you live in the East is to head outside about 6.45am and get to a high place to watch the start of the eclipse.
“Make sure you have a clear line of sight to the horizon in the west-northwest, opposite from where the Sun will rise.”
The NASA map above shows what time each stage of the eclipse starts in different time zones across the United States.
Those who aren’t able to watch the eclipse live can stream the entire event online.
Robotic telescope service Slooh will be livecasting the entire eclipse from 5.45am EST on January 31 (2.45am PT).
