for some reason the clock stopped at 8.39am (7.39am GMT). Surely not a pigeon? See this <[link]> for a 6-minute zoom in of pendulum amplitude (each dot is a 3-second tick). Rather curious that it stopped for about 20 seconds then ran on fine for about 60 seconds and then stopped for good. One theory is that the minute and hour hands interfere with each other as they pass, but these photos [link] [link] taken at 8.44am a few weeks later seem to show that it's OK
