Mercury transited the face of the Sun on May 9th. The entire event was visible from the east coast of the United States, but on the west coast where I am the event had already started at Sunrise and was over by about noon.
I happened to be travelling at the time, so I was unable to photograph the event with my hydrogen alpha setup. Instead I rented a Canon 100-400mm lens and 2x teleconverter to which I attached a 77mm filter with some Baader solar film. Unfortunately, I forgot to bring my tripod on the trip (left it right next to the door..yeah!), so I had to rely on the image stabilization and resting the lens on the roof of my car. I got a couple half decent shots of Mercury with a nice patch of sunspots.
The darker spot in the lower right is Mercury.
