Mercury, moon and beehive cluster to shine in rare August morning alignment – Check date here

Stargazers are in for a rare celestial treat this month. Mercury, a thin crescent moon, and the Beehive Cluster will appear together before sunrise.

Mercury reaches greatest western elongation
On Tuesday, 19 August, Mercury reaches its greatest western elongation. This is its farthest apparent distance from the sun, making it easier to spot. Look low toward the east-northeast horizon about 45 minutes before sunrise. Venus will appear first, followed slightly lower by Mercury, shining at magnitude -0.3.

Astronomers note Mercury is often difficult to see. Even Copernicus reportedly never observed it. Its proximity to the sun usually hides it, requiring careful timing for observation.

Slender moon guides skywatchers on Thursday
On Thursday, 21 August, the very thin crescent moon will help locate Mercury. The lunar sliver, only 4% illuminated, will sit five degrees above the planet. Binoculars will improve visibility, but Mercury should be visible to the unaided eye.
