It looks like the launch was delayed (because of some problem with the launcher?)

Checking Weibo, one insider has just posted several tweets that indicated that something has happened to this launch, but it's not clear whether that means a scrub or failed en route. Either way, this launch isn't our imagination.  :-X

So it is apparent that the launch did took place.....

No signs of any new things in orbit?

That second photo looks like the top of the first stage.

The location of debris recovery in Shanyang county is coherent with CZ-4C 1st stage debris

No TLEs and no launch announcement... Looks like the first launch failure of 2016.

No TLEs and no launch announcement... Looks like the first launch failure of 2016.

....and half a day later it seems like the Chinese simply swept it under the rug as if nothing has happened (in 2009/11/13 they at least did acknowledge within 7 hours). That's very bad precedence...... :-X

Remember anything else other than a third stage problem will directly impact TG-2 and SZ-11's schedule, just like what happened 5 years ago. They will have to explain later anyway so why?

Doesn't seem to have been a 1st stage problem since the debris were recovered where they were expected

http://www.chinaspaceflight.com/satellite/Gaofen/GF-10/GF10-launch.html claims a 18:55 UTC launch time. I'm not sure what's the source, or whether the photos on that page are from this launch.

Google translation:

Satellite score on the 10th at 2:55 on September 1, 2016, by the four C march off from the Taiyuan Satellite Launch Center. Not orbit failure

A rocket work

2016 The first global launch failure.

Looking closer, there is a minimum distance of 18 km between Shanyang county (where this CZ-4C 1st stage debris were recovered) and locations where 1st stages for past successful CZ-4C launches where recovered (i.e. YZ-15 & YG-27)
Not sure if this is significant...
