Probably good time to bump the thread because it looks like this launch is likely to happen within the next few days (maybe even within the next day) - especially given that the tracking ship Yuan Wang 5 is being tracked in Timor Sea today (after moving from its spot south of Bali for tracking the CBERS-4 launch 2 days ago). Another YG-9 triplet?

I don't recall NOTAMs for any of the 4 CZ-4 launches out of JSLC, so....

Ok, let's keep an eye on that in the next days (hours).

Yes, and if someone does notice a NOTAM or info on a projected T-0, please PM me, so I can make sure I get Rui's article on in a timely fashion! Thanks!

Showing what seems to be a CZ-4C launch heading towards a 63.4 degree orbit at around 19:30 UTC today.
So this looks like another YG triplet.

At 19:30UTC today the orbital plane of the Yaogan 16 triplet is directly over JSLC and the NOTAM areas.
This is in line with the Yaogan 20 triplet being launched into exactly the same orbital plane as Yaogan 9. These two triplets are now exactly half an orbit apart, so it will be likely that Yaogan 25 will do the same with respect to Yaogan 16.
It is also interesting that the RA of the ascending nodes of the three orbital planes that are in use are not spread over a full circle. The Yaogan 9/20 orbital plane is 71 deg West of Yaogan 17, while Yaogan 16 is 75 deg East of Yaogan 9/20.

Interesting. So we'll be on the look out for the first TLEs for an inclination of 63.4° and a RAAN of about 318°

This should have launched some time ago (in fact S/C sep. may already be happening as I speak). Standing by...

First orbital elements on Space-Track. Only one object catalogued [40341/14080D], probably the upper stage. The payloads will probably get 40338, 40339 and 40340 as objects A, B and C.
Orbit is 908x1102 km at 63.46 deg, RAAN at 320.48 deg.
