| Apr 13, 2018 at 12:43 | comment | added | Uwe | The sudden loss of altitude looks like about 3 km instead of 30 km. | |
| Apr 12, 2018 at 14:20 | comment | added | uhoh | @Uwe I've used Skyfield which contains a standard SGP4 propagator. Similar scripts that I've posted here and here show how to use it. Since this answer just plots what comes out from running Skyfield (I don't really calculate anything myself here) I didn't post the script in the answer. However here it is: pastebin.com/pR6xt6qg | |

| Apr 12, 2018 at 1:00 | comment | added | uhoh | @OrganicMarble updated plot, I found a drop, though not as dramatic as first "hoped for". | |
