Seems to have disappeared from Nextspaceflight
https://nextspaceflight.com/launches/?page=1&search=SpaceX

(though https://www.spacelaunchschedule.com/category/vandenberg-sfb/ still has it. Seems like there should be time to do it mid/late Oct and allow time for JPSS 1 Nov?)

So has it been delayed? And if so, do we know why?

Maybe SpaceX isn't ready to launch Starlink 4-31 sufficiently before Nov 1 and has chosen to delay it until afterwards?

There's apparently schedule room in November between JPSS-2 on Nov 1 and SWOT on Dec 5.

IDK why the NextSpaceFlight listing has vanished.  ???

Depending on how one counts, SpaceX is just 2-4 launches away from completing Shell #4. I'm not actually sure if the FCC deployment requirements specify that all planned satellites have to be concurrently working in orbit, or merely launched at some point. If the latter, then SpaceX is exactly two 54-satellite launches away from having launched 1584 Group 4 satellites.

I personally suspect/hope that SpaceX will actually ensure that it has the maximum possible number of working satellites in orbit, which would require ~4 more launches. In that vein, Group 1 may also need 2-3 more launches to be truly complete. But it's entirely possibly that both Group 1 and 4 can be considered practically complete after just a few more launches.

I don't think it was removed, it actually hasn't been added to Next Spaceflight yet.

Seems like SpaceX will have room for one (or dare I suggest two) additional Vandenberg launches come November.
If you're happy and you know it,
It's your med's!

So far there's no new NGA notice to support that.  I wonder if he got confused when doing the date adjustment and adjusted the date for UTC (instead of EDT+PDT) to the 27th, then adjusted EDT+PDT to the 26th.
