70 second second stage burn, which seems longer than usual. I predict a significant inclination reduction for the transfer orbit. It should have excess performance because of the low mass (3.5 tonnes). They could use it for a super-synchronous apogee or inclination reduction, but I'm guessing the latter.

Really low parking orbit as well (about 175 km). Good for performance, but potentially risky for the satellite. If the satellite cannot fire up its engines within a few orbits, it risks re-entering. A higher parking orbit means a higher transfer orbit perigee, which gives more time for debugging if anything goes wrong. F9 second stage should re-enter very quickly - no explicit re-entry burn should be needed.

When telemetry was regained after SECO-2 at T+30 minutes, 50 seconds, the maximum velocity was 35,154 kilometers per hour and the altitude was 471 kilometers. That was 167 seconds after the planned SECO-2 time of T+28 minutes, 3 seconds.
Using the Koreasat 5A mission as a basis, the SECO-2 time of that mission was T+27 minutes, 52 seconds (altitude 306 kilometers, velocity 35,546 kilometers per hour). 167 seconds later was at T+30 minutes, 39 seconds. Altitude and velocity at that time were 469 kilometers and 35,051 kilometers per hour.
And Koreasat 5A was 200 kilograms heavier than Turksat 5A. Given that the apogee of Koreasat 5A's GTO was more than 50,000 kilometers, could Turksat 5A have gone a bit higher than that?

Surprised SpaceX has yet to comment on the launch when it’s happening today.hopefully we get word soon.
There were some protests asking SpaceX to drop this customer due to the recent war in Nagorno Karabakh in which Turkey was involved - so I expect them to keep the mission-related announcements relatively low-profile.
That makes sense. Good thing the war is over, though.

I get 1540.6 m/s to GEO for Object A and 1539.9 m/s to GEO for Object B.
