Follow-on to:
For YG-31-02 we should have a more solid date once the Yuan Wang 7 tracking ship moves to its position (Timor Sea?). It's currently moving to the east of Philippines.

In fact YW-7 has already arrived at the usual spot in the Timor Sea for JSLC 63 degrees inclination launches since yesterday.
This launch can happen any time now, perhaps even today. Yet there's nothing else that can prove its existence...

I'm confused by the color of the plumes in the photos above.
The photos near the pad show N2O4 / UDMH coloring but not the photo showing no apparent plume, nor the one showing a white plume. How does that work? Is the coloring of the plume near the pad from some source other than the propellant (e.g. dust)?

http://www.xinhuanet.com/english/2021-01/29/c_139706736.htmChina launches new remote sensing satellites
2021-01-29 13:45:09
JIUQUAN, Jan. 29 (Xinhua) -- The second group of China's Yaogan-31 remote sensing satellites were sent into space from the Jiuquan Satellite Launch Center in northwest China on Friday at 12:47 p.m. (Beijing Time).
The satellites were carried by a Long March-4C rocket. It was the 359th flight mission of the Long March carrier rocket series, the launch center said.
Having entered their planned orbits, the satellites will be used for electromagnetic environment surveys and other related technology tests.
China launched the first group of the Yaogan-31 remote sensing satellites in 2018.

Shanghai Aerospace quotes a different task for the satellites -- sort of strange.
主要用于科学试验研究、海洋和陆地资源普查等任务
They are mainly used for scientific experiment research, marine and terrestrial surveys and other tasks
