See a dawn triple conjunction and a lunar occultation on 31 January

22 January 2019 Ade Ashford

Skywatchers in the UK and Western Europe should look low to the south-southeast an hour before sunrise on 31 January to see a beautiful naked-eye conjunction of Venus, the old crescent Moon and Jupiter, all within a span of 8½ degrees. But if you have a telescope and live in just the right place, you can also see the Moon hide a double star.

The Moon hides Venus in the morning sky

4 April 2016 Ade Ashford

On the morning of Wednesday, 6 April experienced observers in the British Isles with a clear sky living south of a line drawn between Galway in Ireland, Dumfries in Scotland and Berwick-upon-Tweed in Northumberland can potentially observe planet Venus slip behind the northern polar regions of the 28-day-old waning crescent Moon. But beware: the Sun lies just 16 degrees away.

28 November 2015 Ade Ashford

Early risers in the northeast of England and Scotland with clear skies can see naked-eye star lambda (λ) Geminorum, otherwise known as Alkibash, slip behind the southern polar regions of an 18-day-old waning gibbous Moon close to 5am GMT on Sunday, 29 November. However, for a select number of northern observers this will be a special grazing lunar occultation.
