Morning Skywatch: Catch Mercury's Best Show of the Year

When to See Mercury

This week offers one of the better opportunities of the year to catch a glimpse of the solar system’s innermost world. Trapped in its small orbit, Mercury never strays far from the sun, meaning it is usually lost to the light of dawn or dusk. On [specific date], however, the planet reached its greatest western elongation, marking one of the best viewing opportunities this year. The next few mornings offer a chance to observe Mercury as it steadily brightens and improves the contrast with the gathering dawn.

An early start and an unobstructed view towards the east-north-east will be essential for making the sighting. The chart provided shows the view looking in this direction from London at 04:30 BST on Tuesday. If your line of sight is free from obstructions, Mercury will become visible about a handspan above the horizon some time between 04:30 and 05:00 AM.

Binoculars can help in locating the small dot of light, but it's important to stop using them well before sunrise. Sunrise on Tuesday from London occurs at [sunrise time], so exercise caution and make sure to cease using binoculars about half an hour before this time.
