It's a long time since a KSC Starlink launch time that was so close after sunset at KSC. That typically means that the train is visible over the US for the initial period of a few days before "Knife-edge" mode is entered which reduces the visibility of the spacecraft during the holding orbit and ascent. I had wondered whether launch timings avoiding this time of day was a deliberate move to reduce complaints from US residents. The period around dawn was not avoided as a launch time, presumably because fewer people are looking at the sky, if the policy was to control complaint numbers.
