I’ve been keeping track recently and figured I’d post this to see if it’s of use/value or if it’s deemed unnecessary/spam etc . lmk

STARS-EC [47928/98067SE] decayed on April 15 according to space-track.org. We did track it during its final days, but not as extensively as BOBCAT-1. Any reason it is missing from your list?

In general I think warnings of upcoming decays it interesting for SatNOGS.

Also note that the spacetrack module has functions to query the space-track.org decay table, which provides both predictions as actual decay times. Hence, this functionality can be automated.

Random error, I simply missed it while scrolling through the pages. :slight_smile: Edited/added.

Great, thanks for this ^^^ this seems to be the way to go! I seem to gravitate toward doing things the hard way at first for some reason…

Cheers
