A short animation of the second visible pass of the CZ-12 Y1 upper stage (62187) over Australia from 17:08 - 17:15 UTC. The number of visible objects around the upper stage has decreased significantly.


Observing the CZ-12 Y1 upper stage (62187) during the current launch was more interesting. There is currently a lot of stuff flying around the upper stage, possibly ice? It will be interesting to see how the parts behave in the coming hours. Image taken on 2024-12-01 at 06:41:35…

OBJECT A (62185) and OBJECT B (62186) from the Long March 12 maiden launch, recorded today, 2024-12-01 at 06:55:49 UTC over South America. The two satellites appear to be stable, so the deployment and the mission were therefore obviously successful.
