That's not a great day and time too to launch to any known plane of the CX-5/YG-30 triplets.
Thanks, that might align with rumors that the payloads are 2 satellites of the XY-x series instead. But why to a 35-ish degree inclination orbit?

Launch should be happening about now.

Launch success has been confirmed with T-0 at 03:30 UTC.
However....YG-30 is NOT the one riding on this rocket today. Instead we are getting 2 "new technology demonstration" satellites that are reported to "test inter-satellite communications and new Earth observation technologies". The problem is that the name given of the payload doesn't sound like a proper name at all!
I wonder if they are actually demo sats for one of those "Chinese OneWeb/Starlink" plans.....

Thanks Galactic Penguin SST. Images from your link. I've converted the original PNG files to JPG to reduce their size. Bing Translation.
"Successful launch of new technology test binaries in China
CCTV News Client CCTV News client June 27, 2018 11:54
I want to share June 27, 2018 11:30, our country in Xichang Satellite Launch Center with the Long march of the second-C launch vehicle, the successful launch of new technology test binaries, satellite into a predetermined orbit. 2 satellites are mainly used to carry out the satellite link network and New Earth Observation technology test."

So, what are the satellite designations?

Note that there's an interesting bump on the fairing.....
CALT just issued an article that explicitly pointed that out, due to the satellite(s) physical dimensions exceeding the standard fairing. The 2 satellites are stacked on top in series. The article also also call the CAST DFH built satellites "XJSW-A & B" if you follow the usual nomenclatures.

In Pinyin it is
xīn jìshù shìyàn shuāngxīng bāokuò A xīng huò / hé B xīng
新 技术 试验 双星 包括 A 星 和 B 星
Bing translation is
"New technology test binaries include A and B stars"
That would give it the acronym XJSS as the last two characters (双星) are shuāngxīng (literally binary stars or binaries), not weixing. The name is also given on the control screen, the first eight characters of the second line.

"双星 包括 A 星 和 B 星" means "dual satellites including satellite A and satellite B"So I propose to call them XJS-A and B

First TLEs for objects 43518--43520 appeared.
Orbits are lower than the triplets have -- some 475 to 480 km.

This launch could be for PRSS 1.
http://space.skyrocket.de/doc_sdat/prss-1.htm
The information we have says PRSS-1 will be launched from Taiyuan.
I was actually wondering about this one - after all, I haven't seen any public info that PRSS-1 is going into a polar orbit, and some countries near the equator sometimes prefer low inclination LEO for these satellites (e.g. RazakSat for Malaysia and TELEOS-1 for Singapore). Should Pakistan want this, then it would have to be launched from Xichang.
Some guy posted another claim that it is CZ-2C s/n Y44 w/ 2 satellites of the XY-x series though. Dunno of its accuracy.
Y44 - is that confirmed ?
