Moonlight challenges Leonid meteor shower maximum on 18 November

15 November 2019 Ade Ashford

The maximum of the annual Leonid meteor shower is predicted for 11pm GMT (23h UT) on Monday, 18 November 2019. However, the famously swift, bright Leonids — some leaving persistent trails — will have to contend with the glare of a 21-day-old waning gibbous Moon close by visible from 9:30pm GMT to dawn on the 19th.

Watch the Moon hide naked-eye star Zeta (ζ) Tauri on 19 October

When a nearby astronomical body passes between the observer and a more distant object, see say that an occultation is taking place. Since the Moon is our nearest celestial neighbour, it regularly passes in front of planets and stars. Observers in the British Isles can see naked-eye star Zeta (ζ) Tauri glide behind the Moon on Saturday, 19 October 2019.

See the waxing Moon meet the outermost planet on 10 October

6 October 2019 Ade Ashford

The 12-day-old Moon lies in the same low-power binocular field as Neptune late into the evening of Thursday, 10 October 2019 when observers in the UK can find the pair highest in the southern sky against the constellation of Aquarius. The glare of the gibbous Moon will present a challenge, but well worth the attempt to find the outermost planet with modest optical aid.

Depending on where you live in the British Isles, you may be fortunate to view a lunar occultation of naked-eye double star delta (δ) Geminorum at dawn on Tuesday, 27 August 2019. Observers fortunate enough to lie on the so-called graze line will see the star appear to flicker on and off as the mountains and valleys of the northern lunar polar regions drift by.

Have you ever seen the Moon hide a star? If you’re an early riser in the UK with a small telescope on Saturday, 24 August 2019 then you can potentially witness the disappearance and reappearance of three naked-eye stars in the Hyades open star cluster of Taurus between 3:40am BST and shortly after sunrise.

See ringed planet Saturn at its best in July 2019

30 June 2019 Ade Ashford

Observers in Western Europe with a clear sky around local midnight cannot fail to notice the conspicuous ‘star’ that is Jupiter low in the south. But look a span-and-a-half of an outstretched hand at arm’s length to Jupiter’s left and you’ll find another giant of the solar system – Saturn. The ringed planet is closest to Earth for 2019 on 9 July, so here is our quick observing guide.
