Transit of Mercury
On 7th May 2003, the planet Mercury crossed the disk of the sun. This event was witnessed by many Stratford upon Avon Astronomical Society Members.
Dave Rose took multiple CCD images of the Sun, which he combined into a single image, showing the progress of Mercury across the solar disk. Mercury can be seen as the line of dots towards the top of the image. The other objects are sun spots.
An animation made from the component frames of this image can be seen in the Multimedia Gallery.
Steve Smith used an adapted webcam to take various images of the transit through an 8" Schmidt Cassegrain Telescope (SCT). A Thousand Oaks solar filter was used to reduce the light intensity. All the images were taken through thin cloud.

At high magnification, Mercury's tiny disk could clearly be seen...
Mercury will next transit the Sun on 8th November 2006. Before then, on June 8th 2004, Venus will transit the Sun for the first time since 1882.
