On Wednesday 6 June 2012 ASV members keenly observed the Transit of Venus. To celebrate the occasion the ASV held an event in conjunction with the Royal Botanic Gardens Melbourne (pictured to the right) that allowed the general public to experience this rare astronomical event.
Although the last transit was only eight years ago, the next transit of Venus will not occur again until December 2117. There is an excellent fact sheet available from the Astronomical Society of Australia that can be downloaded here.
Fortunately the entire event was visible from most of Australia and New Zealand and many ASV members were able to take images and videos, some of which are presented below.
