Skywatchers across the world will witness the first total lunar eclipse in three years. Here’s who will have the best views—and what gives the moon its eerie red tint.

From the UK, the Worm Moon will rise in the east and will be visible from about 6.40pm on March 14. The Moon will reach its full Moon phase at 6.54am, according to the tracking website Time and Date. This is after moonset, making the best time to spot the Worm Moon the night before and evening after.
