Live coverage of the partial solar eclipse

Observers in Western Europe should look to the east an hour before sunrise on Monday, 18 September to see not only dazzling Venus and the old crescent Moon in the same binocular field of view, but planets Mars and Mercury against the stars of Leo too.

Magnitude +2.9 star Mu (μ) Geminorum, better nown as Tejat in the constellation of Gemini, is occulted (hidden) by the rising 13-day-old waxing gibbous Moon early on the evening of Thursday, 9 January 2020 as seen from the entire British Isles. This is a spectacle for small telescopes and large binoculars, the first bright lunar occultation of a busy year for such events.

With the transit of Mercury just two days away, interest in this comparatively rare event is growing fast. Given the favourable timing of this 7½-hour phenomenon for the UK, many will be able to view it at lunchtime or after work. If you don’t have suitably equipped telescope, join one of the many transit-viewing activities hosted by astronomical organisations nationwide.
