The NASA 2018 page leads to this paper: https://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.

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

@Jean-MariePrival any more luck? There's currently a bounty on this question.

Time evolution data of the Great Red Spot on Jupiter?

# Time evolution data of the Great Red Spot on Jupiter?

(Asked by: username_0 on 2021-01-20)

Jupiter's [Great Red Spot](https://en.wikipedia.org/wiki/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.
