Rhys Morris, Mike Masheder and Alastair Fraser used the optical telescope on the roof of the Physics building (equipped with a solar filter) to take images of the transit. One of their images is shown below; the tiny black dot is Mercury!

Meanwhile, Ben Maughan, Cai Wood and Josie Rawes set up solar telescopes in the gardens for staff and students to use. There was patchy cloud cover throughout the afternoon, but plenty of people managed to see the transit for themselves.

Transits of Mercury happen about 13 times a century, and the next will be on November 13, 2032.
