Jupiter's Great Red Spot fascinates scientists for ages, so it does me. Where can I find a table (e.g. as CSV-file) with the time evolution of longitude, latitude, horizontal and vertical extension of the Great Red Spot? I am sure somebody did already invest the time to extract such a time series from all available (historical) records and images, but it looks like I am searching a needle in a haystack.


There is dozends of nice images and other sources around, for instance:

Longitude and latitude on Jupiter is not so trivial, see F. Bagenal & R. J. Wilson: Jupiter Coordinate Systems from 2016.

    $\begingroup$ The NASA 2018 page leads to this paper: doi.org/10.3847/1538-3881/aaae01 The data for Figure 2 (variations in size and drift rate since 1880) is available as a txt file, but you could easily convert it to csv format. $\endgroup$ Commented Jan 20, 2021 at 11:17

    $\begingroup$ Wow, that's a good start. What about the position of the spot (relative to magnetic reference frame)? That should exist only since recently. $\endgroup$
