After repeated cross-tagging, e.g. in the CatNr range 68993 to 69003, the GP data for these objects now seems to remain stable. Gemini-Pollux CatNr now remains 69000. @tskelso.bsky.social @planet4589.bsky.social

I can confirm that QO-100 is still hanging out at its usual location 😀 My first optical satellite tracking observation. @amsat-dl.org

Apparently 18thSDS has some issues with determining the correct GP data of several objects, e.g. 68998 to 69003. The GP data shows large jumps over time. Therefore the data for Gemini-Pollux, likely CatNr 69000, is not valid most of the time. @tskelso.bsky.social @planet4589.bsky.social
