Observed launch from 100 miles out with 4" telescope. Saw perfect first stage burn, staging, F9US ignition, fairing sep.

Booster did not appear to passivate/vent after staging, but reoriented and appeared to reignite, which surprised.

Fairing halves didn't tumble but kept orientation for minutes after seperation.

Clouds obscured further downrange.

Note: Centaur uses a lot more props on engine start than F9US - sequencing was a lot faster.

Absolutely incredible. OMG!!! Launch was sensational. Then the sun lit up the plume. WOW. But it was just getting started. Stage sep and boostback had the usual amazing effects at night. However, the sun lit up the fairings. I could see both for over two minutes. One all the way through reentry. Eventually the hills blocked it. Then there was the first stage. The sun lit it up against a black backdrop. I saw that the whole way until the hill got in the way. Nitrogen thrusters visible, but the entry burn from a couple hundred miles away was the highlight of the night. WOW WOW WOW!! Never expected to see that today. Speechless.

Words cannot do this justice.
