Waiting on the SF flow. No movement towards this milestone at this time, so we'll know if they can make required <> Tuesday target (to make the 25th) when the TEL moves.

Usual routine. Look for a booster on the pad and we go from there. Static Fire test will be either Tuesday or Wednesday - weather permitting.

So how are we all reading this:

@EmreKelly
Launch hazard area issued for this weekend's #SpaceX Telstar 18V launch from CCAFS. Teams targeting early Sunday (9/9) for liftoff, followed by OCISLY drone ship landing. LHA in effect from 2115 ET on 9/8 to 0400 ET on 9/9 (0015 to 0800 UTC).
https://twitter.com/EmreKelly/status/1037014420717744128

Not sure if I'm reading this right.  So launch has adjusted a few minutes, which now puts it just after midnight EDT on Sunday, 9 September?  Or are we still at roughly 23:23 EDT on 8 September and this another one of the 45th's EDT/UTC mismatches?

What's the throwing me is the "Rescheduled to 09 Sept" reference AND the green Safety Zone B - which I seem to recall goes live 90mins before window open.  If it goes live at 22:43 EDT on 8 Sept., that places window open at 00:13 EDT on 9 Sept. now.

Update to this: 45th's use of 9/9 is based on UTC times, so if you're local, the launch window will actually open on Saturday, 9/8 at 2328 ET (0328 UTC).

Telstar-18V Launch Hazard Areas based on issued NOTMAR/NOTAM messages, valid for Sep 09 (alternatively Sep 10) 03:23-07:59 UTC.

Appropriate FCC application for SpaceX Mission 1398 states planned ASDS position for B1049 landing 655km downrange.

Launch weather forecast is 60% GO (the long launch window will hopefully make it easier):

Launch day probability of violating launch weather constraints: 40%
Primary concern(s): Thick Cloud Layer Rule, Cumulus Cloud Rule

Delay day probability of violating launch weather constraints: 40%
Primary concern(s): Thick Cloud Layer Rule, Cumulus Cloud Rule

Static Fire. Wind must have stopped Alica's view of seeing it, but we have people who have a closer view noting it fired up.

Side note for Saturday's #SpaceX launch: It's not the heaviest #Falcon9 payload to date, which was secured by TELSTAR 19V in July at 7,075 kg, but it's close – TELSTAR 18V's launch mass clocks in at 7,060 kg. Destination is GTO and will serve Asia + Pacific.
