A big thanks goes to Andrew from NSWRA for shooting the following photos of the Acceleron V booster in flight. We didn't get any still photos of the launch on the day as we were busy shooting video. (click on the images for a higher res version)
In the first one you can see the turbulent flow from the red and blue nozzles, whereas the green nozzle has very nice laminar flow (seen further down the plume).
The second photo is my favorite one with the air pulse starting and the sun reflecting from the sustainer.
The last one shows the rocket shortly after staging occurred. The black fins of the sustainer are about to clear the nose of the booster.
I'll post some of the other photos of the flight in next main page update.
