See the waning crescent Moon meet the dawn planets, 15–16 April 2020

There’s a lot of planetary activity in the dawn sky in mid-April. If you’re an early riser in the British Isles, let the waning crescent Moon be your guide to the naked-eye planets Jupiter, Saturn and Mars on 15 and 16 April 2020. Typical 7×50 or 10×50 binoculars will show these attractive conjunctions well, while the smallest of telescopes also reveal some of Jupiter’s bright Galilean moons.

Don’t miss the largest supermoon of 2020 on 8 April

The full Moon of 8 April 2020 occurs just 8½ hours after perigee, its closest point to Earth in the oval-shaped lunar orbit. A full Moon occurring close to perigee is popularly called a supermoon, and this one will be 8½ percent larger than average. This is also the closest full Moon of the year and we’ll not see one larger until 5 November 2025.

Get ready for Comet ATLAS (C/2019 Y4) in the northern spring sky!

Comet C/2019 Y4 was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) on 28 December last year and brightened 6000-fold in just two months to attain magnitude +7.5 on 1 April. Alas, the comet’s nucleus has now fragmented, dashing hopes for a conspicuous naked-eye spectacle in the constellation of Perseus. Here’s our telescopic observing guide.
