Transit of Mercury 2016 – first & second contact – in white light by member Andy Smith. The specific times for each frame left to right are: 12:14:19 BST – 12:14:50 BST – 12:15:11 BST – 12:15:22 BST – 12:15:53 BST
On Monday May 9th 2016, CMHASD held an Open Day at the Parsonage Lane Pavilion, for CMHASD members & for members of the public to hopefully view the rare spectacle of the Transit of Mercury; when Mercury passes between Earth and the Sun.
It turned out to be an absolutely fantastic day and one that people who were there will not forget.
It was a warm sunny day with clear skies at the start and come 12.12pm BST we were rewarded with the first views of the planet Mercury with first contact, passing the Sun’s eastern limb & all in front of a huge prominence too!!!
Members used a variety of techniques to view & image the transit for nearly 3 hours (with a few breaks due to cloud cover) until a little after 3pm when it started to rain. Mercury looked wonderful against the backdrop of the Sun, a little uniform black dot making its way across the face of the Sun. There was no mistaking it for a sunspot either because it was so clearly uniformly black & round. It was visually easy to spot too despite fears it may not be seen that well which was pleasing for those members who were visually observing rather than imaging. There was no missing or mistaking that little black dot!
As you will see from the first photo below, taken by Chairman Simon Dawes, lots of people were there that day and a good time was had by all.
CMHASD would like to thank publicity officer & trustee Honor Wheeler for organising the day – it was a super day.
CMHASD would also like to thank the following members for sharing their photos & images below…Simon Dawes, Andy Smith, Dr Mike Rushton, Martin Crow, Honor Wheeler, Diane Clarke, Gordon Collings & David Freed.
