1582-1598 Tycho Brahé: Realised the first graph of auroras annual number

1716-1732 Celsius: Found than when the auroras borealis appears, the needle of the compass change of direction .


1829-1830 Hansteen: Measurement of the auroras height with triangular method.

1817 Jean Baptiste Biot: study of the auroras polarization.


1870 Tromholt: Found a link between the auroras frequency and the solar spots.
