I am digging deep in @planet4589.bsky.social's catalogues for making some plots on satellite usage over time, and so grateful for his meticulous record keeping that he shares with everyone!

His excellent websites are here https://planet4589.org/index.html, and he's still in the process of rebuilding his full library after moving out of the US. If you happen to be looking for (yet another) good cause to donate to, here's a link: https://www.gofundme.com/f/fund-jonathans-space-report-library-transition
