> Hi ! I would like to know if you have recorded some variation of the trace of your pendulum during the eclipse. Thank you ! Giovanni < Hmm, yes I have. Before the eclipse the rotation of the azimut seemed to have a fixed rate. During the eclipse, this rate seemed to be near zero. However, I am not very happy about the accuracy of my measurements. One should really spend months on this experiment and considerable money to perfect the measurements, and not a few hours, as I have done. One should not place too much trust in my measurements. If anything, these experiments gives you a healthy respect for the effect of hinges and suspensions on pendulums, which can be transferred to seismometers. It is very diffucult to make a perfect suspension, and I wont claim that I succeeded in this.
