Short summary

We report on the history and recent developments of the Tatuoca magnetic observatory in Brazil. This observatory is located close to the geomagnetic equator and within a region of strong main field dynamics. Starting from 2015, we have installed new instrumentation and a new datalogger system. In the paper, we also comment on the challenges of doing absolute measurements at the geomagnetic equator.
