I saw it too William. I watched the launch live on NASA TV and then went outside with a pair of binoculars. There was some broken cloud but then it appeared just as you described. I was expecting 2 points of light so when the binos showed four points travelling together at some speed I initially wondered if I was watching the lights of an aircraft! Anyway it was quite special to watch the launch and then about 20 minutes later to see the vehicle and its second stage pass through my evening sky. Thanks very much for posting the details in advance.
