The next Group 9 or 11 launch, NET mid February, could be this one.  Or, it could be the 8th launch of Future Proliferated Architecture (NROL-192).

Preceding launch: Starlink 11-9 on February 9 UTC.

As of what we know today, NROL-57 can also have been the Jan 21st Starlink launch extra satellites.

Somewhat strange notice but does seem to be for this launch based on timings. I have not received any notices for NROL-57, the launch before 15-1 from SLC-4E yet.

Booster re-entry seems consistent with 70 degree inclination?

Perhaps the first launch of the updated Gen. 1 satellites?

SpaceX is targeting Saturday, February 22 for a Falcon 9 launch of 22 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. Liftoff is targeted for 3:43 p.m. PT, with backup opportunities available until 5:10 p.m. PT. If needed, additional launch opportunities are also available on Sunday, February 23 starting 2:10 p.m. PT.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This is the 11th flight for the first stage booster supporting this mission, which previously launched USSF-62, OneWeb Launch 20, and eight 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.

There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what residents experience will depend on weather and other conditions.

B1082.11

EDIT: Fixed wrong link.

This is confirmed by Celestrak - would be replacements for the Group 2-x satellites.

After the fact

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

Falcon 9 first stages are now cleared for use up to forty 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:
1081.13  Dec 5
1071.23  Jan 10  Starlink 11-10
1088.3    Jan 14  SPHEREx
1082.11  Jan 21
1063.24  Jan 24
1075.18  Feb 1

Edit February 21: It's B1082.11, skipping B1081.13.

Booster re-entry seems consistent with 70 degree inclination?

Perhaps the first launch of the updated Gen. 1 satellites?

This is confirmed by Celestrak - would be replacements for the Group 2-x satellites.

Since there is no 70 Degree VLEO shells. (only ~97)  These should be headed to ~470km pending regulatory approval for permanent residence.

If I ran a program correctly St George should have a possible jellyfish sighting based upon a 6:38:20 PM MST launch.    Most likely Arizona and southwestern TX location should as well.

For St George it will rise around azimuth 248 degrees and getting up to about eight degrees of elevation as it moves south.

For Phoenix it will rise at ~6:40:20 PM MST around azimuth 280 degrees with maximum elevation of 13 degrees around azimuth 232 degrees.

A 616 PM PST launch should allow that sighting along the southern coast of California and inland and probably down the Baja peninsula.

Note that these times and look angles are based upon trajectory data may be a lower inclination, thus the ground track will be further west with that difference becoming more pronounced the further south you look for it.
