Mercury / Sun Transit

Yesterday was one of those rare occasions where the Earth, Mercury and the Sun lined up so that Mercury could be seen as a tiny dark blob as it came between the Sun and the Earth. As we had virtually clear skies here I had to have a go at photographing the event.

Firstly it should be noted that you should not point a camera or look directly at the Sun without a filter designed for that purpose otherwise both could be damaged beyond repair very quickly. This is the Canon fitted with a solar filter which cuts down the received light about 10,000 times:


On to the photographs.
Even with a 400mm lens the Sun only takes up a small part of the view:


Cropped sections.
The first taken about 1 p.m. local time:
There are two blobs to see.
The tiny planet Mercury is near the edge of the Sun about 9 o'clock.
The other is Sunspot number 2542.

This view was taken about 2.45 p.m. local time:
The position of the Sunspot has moved slightly with the rotation of the Sun.
Mercury has moved further as it transits across the Sun.


  1. I was wondering if you got it. A job well done.

    1. Adrian: Mercury is so small it took a while to work out whether I had managed to get it.

Thank you for visiting. Hope you enjoyed the pictures. Any comment, or correction to any information or identification I get wrong, is most welcome. John
