Whoo! I saw it too. I am in North London and used my Coronado PST to dodge the clouds and see 10 minutes at the start and another 10 at midpoint of the transit. Great images by MoonNut and Steveex2003. Mercury may appear as just a dot in front of the sun but I was very pleased to have seen it. Commiserations to people who didn't get a break in the clouds, the same thing happened to me for the Venus transit years ago. My attempts at imaging through solarfoil produced a white disc with absolutely no dot on it. Back to the drawing board on that one.
