Transit of Mercury


The weather was perfect for the Transit of Mercury today and I was able to follow it from beginning to end. There was an obvious sunspot in the middle of the projected disk and it was bigger than Mercury! In fact, \I was amazed by how small Mercury is. But it was perfectly round and moved perceptibly. It was so small that most of my attempts to photograph it failed. The top photograph has it in towards the top edge above the semi-circular shadow and just right of centre. It was far better live.
