Headline Details: Taurus-1 is a 2U CubeSat project developed by Aerospace System Engineering Research Institute of Shanghai for youth education and amateur radio. The amateur radio station onboard will provide telecommand, telemetry and a FM to codec2 digital audio V/U repeater with 67Hz PL tone.
Planning a launch from Taiyuan Satellite Launch Center on 20th Feb 2018 into a circular SSO at 641 km × 640 km. The following frequencies have been coordinated: telemetry downlink 435.840 MHz, FM repeater downlink 436.760 MHz, FM repeater uplink 145.820 MHz.

Just guessing, but this might be on one of the four KZ-1A launches. I have LS-1 flying in March.

The date falls just 4 days after Chinese New Year - a time when I would least expect a Chinese satellite launch to happen. I doubt the launch date will stick.

The 4 known KZ-1A launches in 2018 are for Jilin 1-09 through Jilin 1-12 and all flying from JSLC. Flying on a CZ-4B, CZ-4C or CZ-6 is more likely this year from TSLC as there are several scheduled.

On the morning of February 9, Beijing Normal University and China Great Wall Industry Group Co., Ltd. signed a cooperation agreement and co-released the implementation plan for the small polar satellite (code: BNU-1).
The "BNU-1" Polar Observing Satellite weighs about 20 kg and is designed to carry three experimental payloads, namely, a large field of view resolution (500 m) Multispectral cameras, high-resolution (5.5m) visible light cameras and AIS (Ship Automatic Identification System) receivers.
The satellite will provide multi-spectral images of 800 km width and 50 m resolution in 500 km near-Earth solar synchronous orbit, Complete coverage observations once a day provide high-quality, high-frequency multispectral remote sensing data for rapidly changing polar regions; medium-to-high-resolution cameras are used for critical shots in specific key areas and provide ground resolution in emergencies 5.5 meters of visible light remote sensing data; AIS receiver can accurately record the ships sent by the ship automatic identification system messages, combined with remote sensing data for a comprehensive analysis of the polar region can provide reliable navigation services to the ice navigation support services.

Perhaps not ZY-2D, but ZY-1-02D?
ZY-2 (Jianbing-3) - like 2000-050A / 2002-049A / 2004-044A
ZY-1-02 - like 2011-079A

Until the moment there is no sign that this launch will take place on the 15th.

Still looking for any hint about a launch tomorrow. Until the moment, nothing new in the Eastern front!

There has been literally nothing about ZY-1-02D in public sources (only mentioned in passing in several places), but assuming it is a one-on-one replacement for 02C, the technical info for it can be found here:
https://directory.eoportal.org/web/eoportal/satellite-missions/v-w-x-y-z/zy-1-02cStill looking for any hint about a launch tomorrow. Until the moment, nothing new in the Eastern front!
Same here. Unfortunately when it comes to Chinese spaceflight, absence of evidence is almost certainly
not evidence of absence.
IF it is indeed launching tomorrow and if it is a direct replacement for ZY-1-02C, look out for T-0 at around 03:26 UTC.

Could this launch be performed without publication of NOTAMs?--Messaging only to those specific flights that would be affected?
That has happened before for some Chinese launches, yes?

Yes, there has already been Chinese launches without prior NOTAMs; in that case ATC controllers interface directly with the affected aircraft

Looks like spaceflightfans.cn has just changed the launch date for this one to December 29, with a question mark. They probably don't have much more info than us.

Interesting! There was a previously announced CZ-4C launch out of Jiuquan for December 29, so maybe there was some confusion at the time between this CZ-4C and the ZY-2D launch (using a CZ-4B) from Taiyuan. With this, it makes room for another CZ-2D from Jiuquan at the end of December maybe with Hongyan or with Gaofen-7 (both with a few more co-passengers).

Following up--this didn't launch on December 15.
Belated cross-post:
To clarify, this is the current situation at the original 3 Chinese launch sites:
<snip>
Taiyuan
- ZY-1-02D on CZ-4B - Nothing has been heard of it so far. spaceflightfans.cn current list this on December 29, but with a question mark.
<snip>
This launch is apparently delayed into 2019.
China launch schedule[/b]
2019
?? - CZ-4B (Y39) - TSLC, LC9 - ZY-2D Ziyuan-2D, Tianyi MV-1, BNU-1
December 19
Caveats:
As of this posting, none of our NSF contributors has posted launch date/time news.
Up-thread, there is mention that NOTAM publication has NOT preceded all Chinese orbital launches.
EDIT: Thanks, GP SST!

The situation for this one is.....still unclear. spaceflightfans.cn now has it firmly listed with Ziyuan-1-02D but with a NET Dec. 30 date and the note that it might end up in 2019.
On the other hand there are official articles after the latest Chinese launch that the CZ-2C, 3 series and 11 have closed out their 2018 schedules - but curiously left out the CZ-4 series (built by a different institute as with the 2D).
We might know more when the next launch happens on the 29th. ¯\_(ツ)_/¯

...and
in official reports on today's CZ-2D launch it was stated that one is China's last satellite launch of 2018, so this one is flying till 2019.

Noting that this COULD be the next orbital launch from Taiyuan on June 22.
There have been no orbital launches from TSLC since that of HY-2B on October 24, 2018--approximately an 68 month gap.
EDITED 4/30: A pair of Tianhui-2 Group 01 satellites launched from Taiyuan aboard a CZ-4B, April 29 UTC--with no prior announcement or information.

This launch could be delayed by the investigation and Return to Flight of the CZ-4 models' common third stage.
The failed launch of Yaogan-33 aboard a CZ-4C, on May 22, was apparently caused by the malfunction of the CZ-4B/4C's common third stage.
Cross-post:
Latest early quick-look rumors points to structural resonance problems between the 3rd stage and the payload - which the source indicates that "these usually pops up with larger payloads where low frequency resonance is big". Not sure if that's a mechanical integrity or a propellant sloshing problem, but it's interesting to see that both GF-10 and YG-33 were rumored/predicted as SAR satellites and that both launch failures were rumored to be at 3rd stage engine re-ignition.
