Lucky observers with clear skies who also happen to live on a line drawn between Porthcawl on the Welsh coast through just south of Birmingham and on to the Lincolnshire Wolds can witness a grazing lunar occultation of naked-eye star Eta (η) Geminorum by the rising 18-day-old waning gibbous Moon just before 10pm GMT on 15 November 2019.
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.
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.
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.
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.
