Tonight, the full moon will slip into Earth’s darkest shadow during a total lunar eclipse and create a stunning ‘blood moon’. This will take place in the early hours of March 3 for skywatchers in the U.S., so make sure you set your alarm!
Lunar eclipses are completely safe to watch with the naked eye; no filters or special glasses are needed (unlike solar eclipses). All you need to do is make sure you find the moon at the right time, sit back, relax and enjoy the remarkable show.

The best views of the lunar eclipse will be from the western half of North America, Australia and the Pacific. U.S. skywatchers in eastern time zones will be able to catch the blood moon just before it sets below the western horizon, but will not be able to watch the entirety of totality.
When to look
The best time to look at the total lunar eclipse will be at 6:33 a.m. EST (1133 GMT) on March 3 during the peak of totality when the moon sits in the deepest part of Earth’s shadow.
But if you have the time, it’s worth getting comfortable and watching the entire eclipse, at least from the partial eclipse phase beginning around 4:50 a.m. EST (0950 GMT), when you’ll be able to see Earth’s shadow gradually take bigger and bigger bites out of the moon. It’ll feel like you’re watching the monthly phases of the moon sped up into just a few hours. Then, at 6:04 a.m. EST (1104 GMT), the moon will turn blood red as it enters the totality phase, which will last for 58 minutes according to Time and Date.
