Correction of -15 seconds for a reverse pigeeon event. It seems that the removal of the weights on the gravity arms (17h30 30 Oct) means that the gravity arms jump more easily, as observed when the maintaining weight is engaged alongside the main driving weight. A Pigeon on the hands at hh:15 will have the same effect as a maintaining weight.

ADJUST: +800 ms/day to 29500 It is clear that the temperature compensation has gone wrong [link] . Quite possibly when we adjusted the regulation nut we managed to jam something in the set of steel/zinc concentric tubes that make up the pendulum [link]
