First record denotes prohibited zone near the launch pad, the other two are, probably, for the first stage and shroud. The trajectory is as expected for a sun-synchronous orbit insertion. I guess the scheduled launch time is 02:42 UTC = 10:42 Beijing time, with descending node pass time of 09:00. And I guess that's JB-6 #04.

Interesting information! The first prohibited zone is, as you    mentionned, centered on JSLC, the second (E Qinghai) is centered 620  km   SSW (azimuth ~195); the third (NW Sichuan) is aligned with the   previous ones about 820 km from JSLC.

Expecting the launch on the next few hours.

It is not usual to China to announce this kind of mission so in advance.

I've got your article on standby to go on Rui :)

Also, if any of us see a launch photo in the Chinese media, please note, and we'll use and accredit.

There is an unofficial information of a launch at 0242 UTC (congrats to Liss for his prediction! :) ).
US observation has now TLE for PRC object 2010-047A/37165

giving an orbit of:
627.3 km x 657.4 km inclined  98.01

This would be a similar orbit as for YG-2/YG-4/YG-7

Usually a couple of hours. Today's official confirmation is longer than usual.
However the successful launch was already announced on 1pm (LT) TV newscast (with still images of the launch)

According to the reporter in the video, this launch also send two small satellites "ZDPS" (Zhe Da Pi Sing, it means Zhejiang University Pico Sat) into the orbit. There are rumors on Chinese wesite that this sat weight 3.5 kilogram with dimension 150mm x 150mm x 150mm and life span for 3 months. Maybe they are too small so that there are no TLEs for them.

Very likely Follow-on versions of Zheda Pixing 1, launched together with YG-2.

There are now three objects cataloged. Since the CZ final stage is often
not cataloged on Yaogan launches, B and C may be the picosats.
