Transit of Venus, 8 June 2004

University of London Observatory was opened to the public for the occasion of the first   Transit of Venus  since 1882.  Here are a few first impressions of activity on the day.  The images of Venus are taken with a digital camera directly from a TV monitor, and our better quality data will take a few days to extract.  Note: BST = UT + 1 hour.

Early morning visitors queueing to see the Transit.

Viewing from the roof terrace of the Wilson Building.  In order to get clear views, Barnet Council had to remove a tree in the line of sight.
