The SpaceX timeline is published, see this tweet: https://twitter.com/TGMetsFan98/status/1074742779216097286 SECO-1 is at 00:08:16 after launch, with the second burn starting at 01:08:51 and ending at 01:09:37 after launch. Spacecraft separation will be at 01:56:17. These timing suggest ~1 hour coast in a parking orbit, then a single burn into a transfer orbit, presumably with a ~20200 km apogee. There is a de-orbit NOTAM published, located in the South Atlantic, West of Africa, which is consistent with this launch profile, where the transfer orbit has its perigee at approximately 25 deg South latitude. During spacecraft separation, and the subsequent CCAM/de-orbit burn, the stack is high above the Pacific between Hawaii and the US. Only Alaska may have visibility of the CCAM/de-orbit burn.
