Glorious view of the train from Bellingham, Washington, USA at roughly 9:45 PM EST. Didn't manage to find a camera in time.
I had never seen a recently-launched train before. An otherworldly sight.

Here is a comparison of the webcast telemetry from Starlink missions 4-25 and 4-27.

1. Starlink 4-26 with its 52 satellite payload appears to have been an experiment, with its longer than usual entry burn reducing booster heating.

2. 4-25 and 4-27 both had the usual 53 satellite payload to a 53.2 degree orbital inclination, and so are more directly comparable. The booster telemetry was essentially the same, although the downlink drop-outs were worse for 4-27.

3. The second stage telemetry was quite different however. Burn times are usually between 362 and 366s, but for 4-27, it was some 13s shorter than the average, at 351s. Acceleration was about 7% greater up until the usual terminal guidance phase, where she appears to have maintained the same throttle setting, for a 10% difference over the last minute of the burn.

150th Falcon 9 v1.2 orbital success. Accomplished using 44 first stages, about 12 of which are still apparently flyable.

List of active F9/ FH side boosters with their current designation:

To show the effect that the Block 5 version of Falcon 9 v1.2 has had, this was by my count the 115th Block 5 Falcon 9 orbital launch since the first on May 18, 2018, a number accomplished using only 19 boosters. I should also note that the 44 boosters mentioned in my first post includes B1028 which was lost in the AMOS 6 on-pad explosion. I also accidentally included B1027, which was a ground test booster only. Thus 150 flights using 42 boosters.

List of active F9/ FH side boosters with their current designation:

B1049.11
B1051.14
B1052.7 (Flew twice as FH side booster, will return to that status later on)
B1053.3 (FH side booster)
B1058.14
B1060.14
B1061.11 West Coast
B1062.10
B1063.7 West Coast
B1067.6
B1069.2
B1071.5 West Coast
B1073.4

A dozen boosters in F9 configuration and expected to fly again in that configuration. 1 flight proven FH side booster.

There are also 10 boosters known to exist but that have not yet flown. 4 FH side boosters (B064, B1065, B1072, and B1075) and 4 FH core boosters (B1066, B1068, B1070, B1074) One booster has an unknown configuration, and there is 1 F9 booster set to fly Crew 5 to the ISS.

Of the dozen, 1049 is a special case, so I don't count it the same. It has been allocated to the next expendable flight, so it will only fly once more, probably because it was built before some design tweaks were done to simplify reusability. The rest of those boosters have indefinitely long remaining lifetimes.

I was fortunate to be in the area due to returning on a Disney Cruise in the morning and headed to KSC visitors center as part of my vacation. Bonus was that I got to watch the launch from the Apollo/Saturn V center. It was absolutely amazing to witness my first live launch. I was able to capture video on my phone from ignition to MECO before losing track of the rocket.

Two interesting tidbits that came from the NASA commentator at the viewing stands. First was that she was really giving a hard sell to come back and see SLS launch at the end of the month, and the second was a brief comment on the 39A pad. She just didn't know about the whole idea of building a pad on a pad. Once again it seems like it is hard to accept the way that SpaceX thinks and operates for people used to Old Space.

CelesTrak has ephemeris-based SupGP data for all 53 satellites from the #Starlink Group 4-27 Launch (2022-101) from Cape Canaveral on Aug 19 at 1921 UTC. STARLINK-4580 currently leads the pack, for pass visibility scheduling:

The table has 2019-074. Starlink 4-27 8/21/2022

Here is the correct view of that table. I neglected to put the International Designator (2022-101) into the search box. Guess I need to make sure I am awake or have more coffee.

ASOG and B1062 are underway towards Port Canaveral, following the Starlink 4-27 mission.

Likely to arrive Monday night or Tuesday dawn.

Doug has returned to Port Canaveral on a rather stunning morning with both fairing halves from Starlink 4-27!

ASOG and B1062 nearly home from Starlink 4-27.

I'd estimate arrival to be around dawn tomorrow, once cruise ship traffic clears.

Appears to currently be approx 2.5 hours away from arriving.

The @SpaceX support vessel A Shortfall of Gravitas (ASOG) with B1062 on deck are into the Port Canaveral entrance channel. Tug Crosby Skipper has the tow.

Welcome back from yet another successful Starlink mission!🚀👍🏻

Falcon 9 Booster B1062-9 (now -10) arriving back in Port Canaveral on A Shortfall of Gravitas, following its launch of Starlink group 4-27.

Notably, Octagrabber has one arm not connected to the Booster. Which is interesting.

B1062 looking nice and sooty after nine flights to space and back. It returned to Port Canaveral this morning after another Starlink mission last week. I think its third flight was probably my favorite.

A couple more views of B1062 as it was berthed at Port Canaveral.
