The second launch of BeiDou-3 GEO satellites.
-
This may be the next launch from Xichang--see "Chinese launch schedule" thread discussion, starting here (https://forum.nasaspaceflight.com/index.php?topic=5060.msg1905018#msg1905018).
A CZ-3B, with no YZ-1 upper stage, is assembled at XSLC.

I think it's LC 2.

I think it's LC 2.
That would be LC2 as LC3 has a crane on top of the adjacent service structure with no mobile service structure to assemble the rocket while LC2 uses the mobile service structure to assemble the rocket as seen in the above images. Also LC2 was used for the launch of the first BeiDou-3 GEO sat back in November of 2018.

Have there been any NOTAMs for this launch yet?

Not yet, and looks like the launch was postponed. Don't know the reason.

The discussion up-thread of the LV on LC2 could have been for Beidou-3 I1Q instead; discussion thread here (https://forum.nasaspaceflight.com/index.php?topic=47090.0).

I'll add it to the article as a "could also be".

Currently target for a launch in February.

As of this posting, there is at least one launch scheduled from either LC2 or 3, circa February 15 or 17.
Launch threads for:
Yaogan-30 Group 06, CZ-2C (https://forum.nasaspaceflight.com/index.php?topic=44685.0)
as yet unknown payload, CZ-2D (https://forum.nasaspaceflight.com/index.php?topic=50062.0)
As such, apparently this launch has been delayed into March.

China launches new BeiDou navigation satellite
http://www.xinhuanet.com/english/2020-03/09/c_138859679.htm

XICHANG, March 7 (Xinhua) -- China launched a new satellite of the BeiDou Navigation Satellite System (BDS) from the Xichang Satellite Launch Center in southwest China's Sichuan Province at 7:55 p.m. Monday (Beijing Time), only one step away from completing the whole global system.
The satellite, the 54th of the BeiDou family, was sent into a geostationary orbit as planned by a Long March-3B carrier rocket.
The satellite and the carrier rocket were developed by the China Academy of Space Technology (CAST) and the China Academy of Launch Vehicle Technology, respectively.
Monday's launch was the 327th mission of the Long March rocket series.

One booster is different from the others. Why?

One booster is different from the others. Why?
My educated guess based on previous population protect plans would be that it is a development test objective likely for its future guided landing system. The stripes are most likely for camera tracking of that boosters behaviour.

You could see the parachute on the top of the booster. It might be the test for parafoil recovery.

In the video you can see the deployment of the parachute.
