Didn't see any debris events (to within my eye accuracy and feed quality!) up to SRB jettison, but noticed a slight roll/yaw a few seconds before they were separated... thrust assymetry again or just nominal tail-off transients?
I noticed the slight motion prior to sep also and had the same thoughts.

MCC calls 'Good config for the burn'.

Based on what I'm hearing, the CDR call was "Houston, Atlantis, roll program with the FCS channel."
thank you!

There's a full analysis of SRB tail-off experience on L2; I'm sure they'll be looking at this one too and hopefully we'll see the results eventually.

Noticed it, too. Easier to see during daylight launches, but we'll have to wait to see if there's anything unusual or not.

Why do they keep cutting off the replays if the thing runs into a cloud or goes out of frame for a second?! Be patient and shows us the whole thing! Grrrr. An irritating quirk easily fixed. Anyone else bothered by that or observing it?
Give them credit for good stuff too, the view from CS-2/TV-7A following up looking right up at the wings was neat as hell and unique; we almost never see that.

I assume that the SRBs have standard loads, so can I assume that the external tank has extra hydrogen+oxygen?
Less payload mass available 
Also, is the loss of signal from the external tank camera due to the higher altitude, or from a different orientation, or something else?
Due to the different inclination, they lost signal in the tracking station (Merritt Island, it was?) earlier than with ISS flights.
Antigua for this launch, IIRC.

I think it was reported as such many months ago, but don't think that turned out to be the case and it was just MILA.

PLT will be working the OMS/RCS post burn reconfig on 5-2.

watching John44's video something fell off after SRB separation.

Reviewing the launch, the PAO guy says Merritt Island, don't know if he's accurate.

A good OMS-2 will do that.

Great launch. I assume that everything is good in orbit. I was just surprised that we ddin't see the ET separation as we have for the ISS missions.

Lawton - lack of ET live imagery was covered in L2 and in articles well ahead of launch day.

Atlantis reports going to OPS 106 and moving into Post Insertion timeline and checklist. No deltas to procedures at this time.

JUST FYI:
The “GH2 OUT P” refers to the gaseous hydrogen outlet pressure. There is an idication for each main engine. We trained the crews – particularly the PLT – to use this is in conjunction with the "GO2 OUT T" as a crosscheck (backup indication) for the throttle settings of the SSMEs (space shuttle main engines). It is found on the SYSS SUMM (system summary) display and can be called is usually called up on the center CRTs (CRT2 or 3) by the Pilot.

The orbit pocket check lists will be unstowed around this time.
