Assuming neither Starlink 8-3 nor 7-19 are the next Vandenberg Falcon 9 launch after Starlink 8-8, then Starlink 8-9 would be that launch.

The next Vandenberg Falcon 9 launch should be NET mid June.

Which first stage will be used for this launch?  (semi-rhetorical question)

Falcon 9 first stages are apparently now cleared for use up to twenty times for non-human spaceflight missions, although that number is apparently more restricted for Cargo Dragon and Cygnus than these other payloads.

Available first stages, with UTC date of most recent recovery:
1075.11   Mar 19
1082.5     May 10
1063.19   May 14
1071.17   May 22 (maybe)

I am interested in what has delayed the use of B1075.11.

Edit June 17: It's B1082.5, skipping over B1075.11 again.

Not always correct, but the FAA ATCSCC Current Operations Plan Advisory now has this launch as June 19 UTC. Earlier today it was still June 14 UTC.

Very good opportunity for Southwestern U.S. launch visibility if it launches on its first opportunity.

Good heads up.   

For the Los Angeles area here are the sun events for 18 June 2024:

Sunset:  8:07 PM PDT
Civil twilight:  8:37 PM PDT
Nautical twilight:  9:13 PM PDT
Astronomical twilight:  9:52 PM PDT

As a rough starting point, a launch at civil twilight may allow the ground observer to have adequately dark skies to see the plume.  It would be much better (darker sky on the ground) as the launch gets later. At some point, the second stage would no longer be sunlit.  That time is unknown to me but let us assume about 9:35 PM PDT.

Here is a positive.  For a given launch time that has the second stage in sunlight, the further east you go the darker the skies are on the ground, which would make a better visual experience.

To illustrate that, here are the sun events for Artesia, NM where the launch jellyfish has been seen:

Sunset:   8:08 PM MDT
Civil twilight:  8:37 PM MDT
Nautical twilight:  9:12 PM MDT
Astronomical twilight:  9:50 PM MDT

An 8:00 PM PDT launch is 9:00 PM MDT in Artesia which is almost nautical twilight.  Much better viewing conditions (darker sky) in this more eastern area. 

I use https://www.sunrisesunset.com/ to determine sun events (sunset/twilight) for various locations.  Use the "Search USA" link on the left to input your location and select months and year.  Then after it creates a calendar go back to the bottom left and select "Modify Settings" and scroll down to choose whichever twilight settings you want and again scroll down and select "Make Calendar."

Booster B1082-5

SpaceX is targeting Tuesday, June 18 for a Falcon 9 launch of 20 Starlink satellites, including 13 with Direct to Cell capabilities, to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Station in California. Liftoff is targeted for 8:00 p.m. PT, with backup opportunities available until 12:00 a.m. PT on Wednesday, June 19. If needed, additional opportunities are also available on Thursday, June 19 starting at 8:00 p.m. ET.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the fifth flight for the first stage booster supporting this mission, which previously launched USSF-62, and three Starlink missions. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean.

Group 7 launched to 53 degree inclination from Vandenberg = 22 V2.0Mini's
Group 9 launched to 53 degree inclination from Vandenberg = 20 Starlinks.

The reduction by two satellites is due to the 13 direct-to-cell Starlinks (unofficial name v2d) being carried, which are a little heavier than the standard mini's (unofficial name v2m). 24 v2m's were launched with 17,500 kg payload [1]. That gives a v2m mass of 729 kg. Solving 22*v2m = 7*v2m+13*v2d, gives a v2d mass of (22-7)*v2m/13 = 841 kg.
