New fabric acoustical protection being used inside the fairings now for more clearance and protection.
Hey my question made the cut!  8)

Great launch.

Congratulations to ULA & partners on a perfect launch!

That 551 does get off the pad in a hurry, doesn't it?  Lovely to watch.

Compared to the 401, it seems to just leap off the pad.

My congrats as well!

I captured something that seems interesting - one of solids barfed a large piece of unburned fuel. Is this normal?

Yes. The STS SRBs did it too.

That solar wing radiator (or was it the photovoltaic panel itself) on the right definitely felt the fairing jettisoning.

Congratulations to ULA and USN for the successful launch! I didn't see a press kit for this launch. Here's a one page flyer from ULA's website.

For those who may want to try to catch the Centaur venting  http://www.satobs.org/seesat/Jun-2016/0097.html

The same observer who found Mentor 7 (with help from veteran observers) photographed venting and the payload.   http://sattrackcam.blogspot.nl/2016/06/muos-5-gto-insertion-and-centaur-fuel.html

1.  I got about 4:30 from the launch replay video--ignition at 0:56, cutoff at 5:26 (not totally accurate due to commentator delay.)  The launch aritcle lists the burn as 4:25.6.

Atlas burns to depletion so no worries about a long burn there.  I guess a really long burn could mean an underperforming powerhead on the engine and thereby gravity losses, but <5s is attributable to other variables.

The burn duration was < 0.25 sec of pre-flight prediction.  As I mentioned in a previous post (in some other thread I can't find), the duration itself doesn't reveal much about performance.  You could have high thrust and high flowrates (nominal ISP), resulting in an earlier BECO, or you could have nominal thrust and high flow rates (lower ISP), resulting in an earlier BECO.  One good, one bad.
A 3-sigma high or low propellant load can also affect BECO time, as the stage burns to depletion.  Really have to see the state vector at BECO.

Amateur observers may have found the payload on the way to it's final orbit.   http://www.satobs.org/seesat/Jul-2016/0014.html
