Short summary

Chambon-la-Forêt magnetic observatory distributes definitive second data that are contaminated by noise with a standard variation below 400 pT. This noise is low compared to the international standard set by INTERMAGNET. It is mainly due to local signals of unknown origins that have short wavelengths in space (less than 200 m) and in time (less than a day).
