The hot performance of the CUS might have been caused by the mixture ratio being a little LOX rich. This increases thrust at the cost of reduced Isp. The LOX will also run out earlier, leaving more LH2 left in the tank than predicted possibly resulting in the reduced delta-V.

SpaceTrack is apparently mixing up GSAT-19 (object A) and the upper stage (object B)
They've finally found the spacecraft in a drift orbit:

With yesterday's TLE, seems stable now at 82.5E.

The last part of S-200 separation is taken from an excellent amateur footage captured from Chennai.

Full video was posted previously here

That fiery separation of the solid boosters was scary indeed, as if the flames had enveloped the entire rocket ! And it was a treat to watch the separated boosters tumble, and the core carrying on with its business as if nothing had happened.

Here is another video of booster separation.  Action starts from 3:02 onwards

That's a great video! (but I wish it was stabilized)

Even GSLV Mk III-D1/GSAT-19 mission brochure did not ever mention about a 3D printed antenna. But it does seem to have one.

( Careful .. no references given .. only reproduction of contents )

BTW this seems to be a test antenna because there is no 300mm antenna aboard as per brochure. ( There is a 1.4M and a 2M antenna as per brochure ).
