^ The Chinese Academy of Sciences' Purple Mountain Observatory based in Nanjing also moved three radio telescopes to an observation post in Suzhou. The radio telescopes could probe the eclipse despite cloud and rain.
geophysicists from the Chinese Academy of Sciences were preparing an array of sensitive instruments at six sites across China ready to take gravity readings on Wednesday, 22 July, as the eclipse passed over the south of the country. The experimenters hope the results, which will be analysed in the coming months, will confirm once and for all that anomalous fluctuations recorded during past eclipses are a real phenomenon, rather than an experimental artefact.
In the run-up to the 22 July eclipse, a team led by Tang Keyun of the Chinese Academy of Sciences prepared eight gravimeters and two pendulums, spread across six monitoring sites (see Map). The researchers hope that the long distance between the sites - roughly 3000 kilometres between the most easterly and most westerly stations - and the number and diversity of instruments will eliminate the chance of instrument error or local atmospheric disturbances.
Each observation site is a China Seismological Bureau station either inside a cave or at a remote location where human disturbance is minimal. The researchers will also monitor changes in air temperature and pressure as well as seismological disturbances that could affect their results.
