As soon as the pitch maneuver begins, as long as they don't have constraints on overflying SLC-6. It wouldn't overfly any inhabited portion of land.

Is my understanding that RF Mission 1-5 is the same as Group 2-1 correct?

Based on this tweet from Jeff Foust ...

https://twitter.com/jeff_foust/status/1435235605559062542

Quote from: Jeff Foust
At Satellite 2021, SpaceX CFO Bret Johnsen says the first Starlink polar launch is coming up in the “next couple of days.” #SATShow

... I wonder if these NGA notices are for this launch.  Note that the second one is also a Rocket Launching notice, but it appears that it should be a Space Debris notice.

Here's a new NGA notice, unrelated to the ones I previously posted.  It's doesn't look like a Starlink launch to me, and it doesn't start on September 13, but it does include September 13.

So it seems they'll have two launch windows about 12 hours apart starting on the 13th, around 9am and 9pm local.  They've done similar things with Starlink launches from Florida before.

Of Course I Still Love You droneship has departed from the Port of Long Beach for SpaceX's first Starlink mission from Vandenberg.

OCISLY will be stationed approximately 639 km downrange.

New cancel-and-replace notices from the NGA.  The afternoon (UTC) launch opportunities have been eliminated, leaving just the morning (UTC) launch opportunities.

Note that the second notice should be Space Debris, not Rocket Launching.

Do you maybe mean that the morning launch opportunities have been eliminated, leaving just the evening ones?

The notice you quoted said "0320Z TO 0446Z DAILY 14 THRU 16 SEP", which I convert as 8:20 PM to 9:46 PM in California on the 13th, 14th, and 15th of September.  Or am I reading that wrong?

EDIT:  Oops.  I reread after posting and I think I misunderstood what you were saying.  I think we are in agreement and you are correct that the afternoon times in UTC (which are the mornings locally in California) that were listed in prior notices have been eliminated.  Meaning that the launch will be in the morning UTC (which is the evening locally in California).  Sorry for confusion.

Per the launch timeline, this Starlink mission will involve a direct-insertion launch profile, meaning Stage 2 could deorbit on the first orbit.

51 - not 60 - satellites, as well. Combined with polar dV losses, that strongly implies that Starlink's "Group 2" laser interlink variant is only marginally heavier than the ~260 kg V1.0 design - maybe 5% but definitely less than 10%.
