| Summary: | The Tatuoca magnetic observatory (IAGA code: TTB) is located on a
small island in the Amazonian delta in the state of Pará, Brazil. Its
location close to the geomagnetic equator and within the South Atlantic
Anomaly offers a high scientific return of the observatory's data. A
joint effort by the National Observatory of Brazil (ON) and the GFZ German
Research Centre for Geosciences (GFZ) was undertaken, starting from 2015 in
order to modernise the observatory with the goal of joining the INTERMAGNET
network and to provide real-time data access. In this paper, we will describe
the history of the observatory, recent improvements, and plans for the near
future. In addition, we will give some comments on absolute observations of
the geomagnetic field near the geomagnetic equator. |
