today installed four thermocouples to measure the temperature down the pendulum shaft. Temperatures now are [15.7 15.2 15.0 11.9 11.9] in degC from bottom to top. the last reading is in the clock chamber . Note that the bottom three readings are where the pendulum swings in the room below - it is clearly warmer there.
