A transit of Mercury took place on the 9th of May 2016, as seen from the Earth. Between 13:12 and 20:42 (local time) the planet was visible as a round, dark silhouette moving across the disk of the Sun. The Department of Astronomy hosted a public event outside AlbaNova showing the transit using different telescopes. The weather was good and we had more than 300 visitors between 12:45 and 18:30. A news feature for TV was also made. We'd like to thank everyone who came to visit us during the transit!

This image of the transit of Mercury was taken May 9th at 17:16 (local time), through a 20 cm telescope equipped with a solar filter. Mercury is visible as a black circle to the left. The whole Sun is not visible, but some sunspots can be seen to the right of Mercury. Solar north is to the right in the image. Exposure time 1/500 s. Photo: Magnus Näslund.
