The NOTAM for Taiyuan, it is a new drop zones, maybe it will be the new CZ-6C? (https://forum.nasaspaceflight.com/index.php?topic=57867.msg2519428#msg2519428)

Wasn't CZ-6C scheduled for December?

I see, maybe CZ-6 or CZ-6A...

The first drop zone within Shanxi boundaries seems too close to TSLC to be for any launchers using only liquid fuel 1st stages (CZ-2/4 series, or CZ-6/6C). It's tough to tell but I think CZ-6A seems to be a plausible candidate. It could also be any of the small SRB-based launchers, but I would expect another drop zone even further downrange than the 2nd one.
Also note that the flight azimuth is pretty close to due south, something like 171-176 degrees, which would put this at a polar, non-SSO orbit.

"Electromagnetic environment probing" and related demonstrations is officially listed as YG-40's purpose, so it's probably a ELINT/SIGNIT/COMMINT satellite(s)?

Yaogan-40 is not one but three satellites built by CAST's DongFangHong.
This Long March 6A is 5.4m taller than previous 2.

👀 CASC says they've signed contracts of 10+ annual launches of Long March 6A and Taiyuan Satellite Launch Center's pad#9A will be able to support 12 launches per year.

China launches new remote sensing satellite
https://english.news.cn/20230910/dec8a245aaf64edfade07844223739f4/c.html
TAIYUAN, Sept. 10 (Xinhua) -- China on Sunday successfully launched a new remote sensing satellite from the Taiyuan Satellite Launch Center in north China's Shanxi Province.
A modified version of the Long March-6 carrier rocket carrying the satellite Yaogan-40 lifted off at 12:30 p.m. (Beijing Time).
The satellite has entered the preset orbit. It will be used for electromagnetic environment detection and related technical tests.
Sunday's launch was the 487th mission undertaken by the Long March rocket series.

This overlay of Long March 6A Y5 and Y1 clearly shows that Y5 has a kind of special long fairing that makes it taller, nearly 55m tall while Y1 and Y2 were about 50m
Edit to add:

And if we align the top of the rocket, we can see that the wider section of the new fairing is actually shorter than previous ones. CASC's press release has mentioned the three Yaogan-40 satellites are in stacked configuration.

So what's between second stage and fairing? A newly introduced third stage?

Five objects at 86 deg 800 km orbit and a rocket stage.

Satellite imagery shows Long March 6A Y5 on the pad just over two hours before it launched three remote sensing satellites into orbit from Taiyuan Satellite Launch Center in China earlier today.

CelesTrak has GP data for 6 objects from the launch (2023-139) of Yaogan-40 atop a Long March-6 rocket from Taiyuan Satellite Launch Center on Sep 10 at 0430 UTC...

It's interesting to note that the USSPACECOM has identified objects A, C, E as satellites even if there is no maneuvers as of today.
