T+90 seconds. Right now, you're looking at an onboard camera mounted on the CCB looking at two of the AJ-60A boosters.

SRB burnout confirmed.

T+1 minute, 40 seconds. Awaiting jettison in ten seconds.

There go the boosters.

ZachS09 · « **Reply #283 on:** 11/19/2016 10:44 pm »

T+1 minute, 52 seconds. All four SRBs have separated cleanly. No attitude disturbances detected.

You can see the limb of the Earth in the onboard camera!

T+2 minutes, 15 seconds. Next major event will be the separation of the 5-meter payload fairing and the Centaur Forward Reactor (CFR) at 3 minutes and 30 seconds.

T+3 minutes. The RD-180 is burning as it should be.

And that was that for the NASA TV coverage of the GOES-R launch.
[YT stream that is.]

NASA TV switched, but back again.

ZachS09 · « **Reply #288 on:** 11/19/2016 10:46 pm »

T+3 minutes, 30 seconds. The payload fairing and Centaur Forward Reactor have both been jettisoned. Looking for Booster Engine Cut Off at 4 minutes and 22 seconds. RD-180 is at 2 Gs beginning to throttle up.

I don't even care about the channel switches anymore.

actually all channels

T+4 minutes. Boost phase chilldown is underway and the RD-180 has throttled to maintain an acceleration of 5 Gs.

We have LOS of the CCB onboard camera.

Guy is trigger happy!

ZachS09 · « **Reply #292 on:** 11/19/2016 10:47 pm »

T+4 minutes, 20 seconds. BECO. Booster Engine Cut Off has occurred. And we stopped boost phase chilldown on time.

ZachS09 · « **Reply #293 on:** 11/19/2016 10:47 pm »

T+4 minutes, 30 seconds. We have stage separation. We have prestart on fuel and LOX. And ignition; full thrust on the RL-10C-1 engine. The GN2 purge firing of the RCS is complete.

Chris Bergin · « **Reply #294 on:** 11/19/2016 10:47 pm »

Staging!

ZachS09 · « **Reply #295 on:** 11/19/2016 10:47 pm »

T+5 minutes. This first burn of the Centaur, the longer of three planned firings, will last 458 seconds (7 minutes and 38 seconds). Centaur MECO-1 will occur at 12 minutes and 16 seconds.

ASOC performing readiness poll for pad entrance.

ZachS09 · « **Reply #298 on:** 11/19/2016 10:48 pm »

Slightly above nominal performance for CCB. So, no MRCV problem.

hearing centaur asking for an slightly higher oxidizer rich mixture
