When the Moon slides in front of a planet or a star: contact times, limb sides and parallax, computed for where you stand.

On 14 September the Moon Wipes Venus From a Daytime Sky

On Monday 14 September around midday, a 12 % crescent Moon will pass in front of Venus, magnitude -4.75, under a Sun standing 40 degrees high. From Paris the planet vanishes at 11:26 and re-emerges at 12:34; from London the Moon rises with Venus already hidden. The disappearance itself takes a minute and a half: Venus is a disc, not a point. City-by-city times, and the method for seeing a planet in daylight.
