The mystery around the missed KJ-satellite from Xi'an University of Electronic Science and Technology,was revealed. This report (http://www.mitron.cn/qynews.html?id=838) confirms that NX-2 mothersatellite from Tsinghua released not two ZJ satellites but ZJ-1 picosatellite (紫荆1号, Tsinghua University, 234g weight) and KJSY-1 picosatellite (空间实验一号, Xi'an University of Electronic Science and Technology, 173g weight).

Has anyone logged a launch code for this flight?   05-48 perhaps, with Yaogan Weixing being 05-47?

From http://lt.cjdby.net/thread-2076904-1-2.html
Apparently some LM-6 debris, with villagers appreciating the new gasoline fumes, instead of the good ole hydrazine

Also, there are tons of threads for this launch here : http://lt.cjdby.net/forum-11-1.html . Looks almost like Chinese equivalent of NSF ..

Hmm, maybe I was wrong, but I thought they used the new HIF to the east of the old Launch Area 7 at 38 50' 51" N, 111 37' 11" E?

Obviously, now they are using new buildings for CZ-2/4 preparation.

For example, Yaogan Weixing-27:

It seems to be really 05-48. Has anybody a higher resolution Image available?

Yes "05-48" is visible

My version of objects identification, in the order of orbital height:

40912 = 2015-049P DCBB = KT-1B
40899 = 2015-049A XY-2 = KT-1A
40900 = 2015-049B PhoneSat (confirmed)
40901 = 2015-049C ZDPX
40902 = 2015-049D ZDPX
40903 = 2015-049E XW-2A (confirmed)
40904 = 2015-049F Luliang-1

40909 = 2015-049L XE-2E (confirmed)
40906 = 2015-049H XE-2C (confirmed)
40911 = 2015-049N XE-2B (confirmed)
40907 = 2015-049J XE-2D (confirmed)
40905 = 2015-049G Naxing-2
40910 = 2015-049M XE-2F (confirmed)
40908 = 2015-049K LilacSat (confirmed)

XW-2E and -2F separated from XW-2C, I believe.

As of Kaituo-2 (also transcribed as Kaita-2), it was mentioned in the artcle http://www.chinanews.com/gn/2015/09-20/7533462.shtml which I think to be official. They listed only six names but in fact they cover almost all 20 sats:

开拓一号、希望二号、天拓三号、纳星二号、皮星二号、紫丁香二号
Kaituo-1, Xiwang-2, Tiantuo-3, Naxing-2, Pixing-2, Zidingxiang-2

That's confusing as KT-1 is also used as the name of a solid fuelled launch vehicle.

To be fair, KT-1 the rocket is actually 开拓者一号 (Pioneer, the noun), while Satellite is 开拓一号 (Pioneer, the verb).  So KT-1 the rocket should really be KTZ-1, but I guess that's too many letters for CASIC.

XW-2A is now in a lower orbit than the other payloads, so presumably has manoeuvre capability.

More payloads now confirmed: ZDPX 2A/B are objects C and D, XY-2 is object F, only question now is which of Luliang 1 and NX-2 are objects A and G.

I still believe NX-2 is G, so Luliang-1 is A. Object B seems to separate from A, not G.
In fact, fantastic job in matching catalog entries with real birds done successfully.

XW-2A continues her downward maneuvers. Does she target the rocket body?

acts similar to KOSMOS-2502

You mean K2499, don't you? In any case, she is Object E of her launch.
Well, I believe I found out which other object she targets.

an interesting paper (currently free) on one of the payloads of this launch:

Flexible attitude control design and on-orbit performance of the ZDPS-2 satellite
http://www.sciencedirect.com/science/article/pii/S0094576516300297

Quote
ZDPS-2, the 2nd generation nano-satellites designed and manufactured by Microsat Research Center of Zhejiang University, were successfully launched by the new generation rocket CZ-6 on Sep 20th, 2015. They are two 20 kg identical nano-satellites (ZDPS-2-A and ZDPS-2-B) with a large deployable mechanism with a truss structure. The main mission of these two satellites is on-orbit demonstration of several new technologies, including large lightweight and flexible deployable mechanisms, a custom-designed panoramic wide field of view micro camera Sun sensor and infrared Earth sensor, and a micro-propulsion system as well as dual-satellite formation flying technology. The satellite is a 25 cm cube with a deployable mechanism, whose fundamental frequency is only approximately 0.13 Hz. This brings several challenges to attitude control. Flexible structure dynamics and its influence on attitude stabilization must be taken into consideration. A robust control scheme is developed by fully utilizing environmental torques with limited control actuator capability. On-orbit performance verified this design. ZDPS-2 satellites have successfully achieved rate damping, sun-pointing control and 3-axis stabilized Earth-pointing control, with a control accuracy of 5 (3σ) and stability superior to 0.1/s (3σ). This paper demonstrates the flexible attitude dynamics modeling, illustrates the attitude control system design of ZDPS-2 and presents the on-orbit performance as well.
