They have the Yaogan-33 in May from TSLC with a CZ-4C to SSO.

If this is not an entirely new "make/model" of Yaogan satellite, then...

This could be a second satellite of the same type as YG-29, a "next-generation" SAR reconnaissance satellite.
It also launched on a CZ-4C from TSLC, LC9, to a SSO (~615 km circ., 97.8 deg.).

Another option is perhaps a sixth in the YG-8 optical reconnaissance satellites (numbers 8, 15, 19, 22, and 27). These satellites have an alternate internal classification, Jianbing-9, or JB-9. The previous five have launched on CZ-4C's, from TSLC, LC9, to a different SSO (~1200 km circ., 100 deg.)

YG-29 launch thread here

YG-27 launch thread here

Also noting: this launch may not be preceded by published NOTAMs.

(EDIT 5/3 no NOTAMs or other navigational notices preceded the April 29 UTC launch of the pair of Tianhui-2 Group 01 satellites from TSLC. EDIT 5/16: NOTAMs posted!)

EDIT 5/24, following post-launch failure discussion down-thread: Gaofen-10 (GF-10) launch failure thread

According to the 9ifly Chinese space forum, this launch will take place around May 20.

By my visual inspection:
The launch azimuth for this launch, determined by NOTAMs, better matches the launch azimuth of YG-29, determined by 1st stage and PLF parts impact sites; rather than the launch azimuth of YG-27, determined by 1st stage impact sites.

Seeking correction, clarification, or confirmation.

Launch should be happening about now.

Launch has happened according to 9ifly!

Come back in about 30 minutes to see if the launch's officially confirmed.

I assume they are talking about a stage coming back, not as literally as the translation makes it sound?

That's my understanding. Meanwhile, on 9ifly they are wondering about the mission (this is from the same person who first reported the launch).

http://www.9ifly.cn/forum.php?mod=redirect&goto=findpost&ptid=92038&pid=655535

"The result of the mission?"

Galactic Penguin SST · « **Reply #18 on:** 05/23/2019 12:56 am »

Rumors out at the Chinese forum I usually visit that there's a launch failure......

The location mentioned above appears to me, by visual inspection of a map of China and the NOTAMs mapped up-thread, to match the location for the 1st stage impact.

Speculating re: the attached image, with the corkscrewed contrail.
I know high-altitude wind shear can quickly distort a rocket's contrail...but, it doesn't look healthy for an orbit-bound LV.

EDIT 5/23 re: contrail--never mind!
