"had been launched."

"Today, the weather is fine, and many people see the process of the fairing falling."

Apparently, a video of the fairing falling. Doesn't play in my browser.

Thanks for the suggestion, but I already have three browsers on my system! Not going to add another one. :-)

Thank catdlr! Here's a screen grab of the last frame.

Photo of the satellite. Article is saying this is the last launch of the year. I count 39 launches from China with one failure. The 37 would be excluding ZQ-1 and KZ-1A.

"The launch was the No. 297 flight of the Long March series of launch vehicles and the last aerospace launch of space science and technology in 2018, with all 37 aerospace launch missions being successful throughout the year, with the number of launches ranking first in the world."

Pieces on the ground.

These are apparently stock photos: the 1st one is from a Xichang launch and the 2nd one is from Shenzhou 10 (note short sleeves).

Apparently this article was prematurely released because the mission is apparently still ongoing at this time - with multiple restart capability and a 48 hours lifetime the YZ-3 upper stage can deploy satellites into many orbits - probably what's going on for this one.

Launch success has been confirmed with T-0 at 08:00 UTC: http://www.chinanews.com/gn/2018/12-29/8716016.shtml

There are only 7 satellites on this flight: Hongyan-1 and the 6 satellites mentioned below:

This thing, built by DFH Shenzhen and has been floating around since first reported around 2-3 years ago (I'll have to dug around for the source), is apparently on board this launch. Let's see if more info will come out post launch.....

.....which was collectively given the name Yunhai-2.

As launch code appears to be "01-99" what is the launch code for the previous launch out of JSLC (Saudisat, Dec 7)?
