Transit of Mercury

Transit of Mercury on November 11th 2019

Its not too long to go now before the Solar System's innermost planet, Mercury, will cross the face of our Sun around lunchtime on Monday 11th November. Mercury's transit will begin around 12:35h GMT. The time of greatest transit, that is when Mercury "is near the middle of Sun" is around 15:19hGMT, and the transit event ends around 1804h GMT. However on that day, the Sun sets around 16:15h GMT for the UK so we won't be able to see the end of this event. 

The image below shows the approximate path of Mercury across the Sun and the times of 1st contact, time of greatest transit and the position of Mercury on the face of the Sun at sunset here in the UK.
