Seems like January 9 is now confirmed as the target:

A0049/17 - A TEMPORARY RESTRICTED AREA ESTABLISHED BOUNDED BY:N304059E0974550-N304323E0973336-N312020E0974316-N311756E0975534 BACK TO START. VERTICAL LIMITS:GND-UNL. GND - UNL, 09 JAN 04:12 2017 UNTIL 09 JAN 05:22 2017. CREATED: 05 JAN 06:04 2017

Also the official website for the KZ series, of which the preview version was found back in Christmas, is now live......without the user manual.  ;) http://www.expace.com.cn/index_16.aspx

We could really use some photos, anything, even in processing, of this vehicle. I'm struggling ;)

Nothing reported yet about this - though I don't expect anything otherwise for something that is very much a mobile ICBM in the middle of the desert.  :P

There might be a chance the website of EXSPACE might announce the launch faster than the state media so watch out for that too. ;)

Here's a video of the launch from some distance away from the "pad" (haven't found the original source yet): https://twitter.com/cnspaceflight/status/818327419559952384

China launches commercial rocket mission Kuaizhou-1A
 http://news.xinhuanet.com/english/2017-01/09/c_135967088.htm

JIUQUAN, Gansu, Jan. 9 (Xinhua) -- The rocket Kuaizhou-1A (KZ-1A) has sent three satellites into space in its first commercial mission on Monday.

The rocket, carrying the satellite JL-1 and two CubeSats XY-S1 and Caton-1, blasted off from northwestern China's Jiuquan Satellite Launch Center at around 12:11 p.m. Monday Beijing Time, according to a statement from the center.

The KZ-1A was developed from the Kuaizhou-1 rocket with improvements in adaptability. It is a low-cost solid-fuelled carrier rocket with high reliability and short preparation period and was designed to launch low-orbit satellites weighing under 300 kg.

The JL-1 is a multifunctional remote-sensing satellite providing high-definition video images which is expected to be used for land resource and forestry surveying, environmental protection, transport and disaster prevention and relief purposes.

The XY-S1 and Caton-1 are experimental satellites to test technologies of low-orbit narrow-band communication and VHF Data Exchange System (VDES) respectively.

A rocket technology company under the China Aerospace Science and Industry Corporation was responsible for the launch mission. The success of the mission marks the company's capability of providing flexible, convenient, quick and economical launch services for domestic and overseas clients, said the statement.

Objects 41913--41916.
Good circular orbit it seems.

From the Users Guide, the N2O4/MMH bipropellant fourth stage "Propulsion Control Module" appears to perform an initial separation burn from the third stage, followed by a several minute coast and, finally, a 5 to 6 minute long insertion burn for 700 km SSO missions.  At 0.4 g maximum acceleration, I would guess that the propulsion system provides 100 to 200 kgf thrust.  The module also appears to provide pitch/yaw/roll control during Stage 2 and 3 phases, including coast.

Any information on the solid motor stage thrusts?
