Watched this last night on the live Youtube tracking site, and watched as it's elliptical orbit altitude varied and how each orbit got lower. 

But as they twice changed the estimated atmosphere entry time and it was getting on for 3.30am gave up and went to bed.

Understand it came down around that time in the Indian Ocean west of the Maldives.

Spent Chinese rocket stage set to make an uncontrolled return to Earth

The spent booster stage responsible for placing the first module of China's next space station into orbit is set to make an uncontrolled rendezvous with Earth.

The first module of Tiangong-3, "Tianhe", was launched at the end of April atop a Long March 5B rocket and is currently safely in orbit.

The same, alas, cannot be said for the Long March 5B (CZ-5B), which features a core stage and four strapped-on liquid fuelled boosters. The rocket is capable of injecting a payload directly into low Earth orbit but, unfortunately, does not appear to have much in the way of self-disposal.

      Just a quick update/reminder ..... as the Hall will NOT be open, suggest you bring along your own refreshments for the evening. As well as your telescopes, binos, and masks. Don`t forget, this is limited to thirty persons only as per the Govt guidelines.

     See you there, Doug.

Bring your details on a slip of paper, hand it to Rose and then she can enter it onto the Observing evening register, which we keep. Look forward to seeing you all .... don`t forget that there can only be thirty people at the Observing evening.

Cheers, Doug.

Thank you Carole, Fay!

Duncan, yes! I tried to keep the picture as it looked in the eyepiece. This region was close to the terminator and full of shadows and some bright spots.
Thanks

Roberto
