Background
A SpaceX Falcon 9 Rocket will launch a series of Starlink v1.5 satellites deployed into Starlink's second generation constellation from Vandenberg Space Force Base.

Hazard Area Evaluation
The National Airspace System (NAS) hazard area evaluation examined three Aircraft Hazard Areas (AHAs) associated with the launch of Starlink 11-4. The first, AHA-A, extends from the launch site to 125nm southeast. AHA A is contained within the Los Angeles FIR. The second AHA extends from 273nm southeast of the launch site to 400nm southeast and is contained within the Mexico FIR (MMFR). The third AHA is associated with the 2nd Stage Reentry and is located west of South America and lies within the KZAK, MMFO, NTTT, NO FIR XX01, and SCIZ FIRs.

[zubenelgenubi]

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
1063.23  Dec 17  Starlink 11-6
1075.17  Dec 29
1071.23  Jan 10
1088.3    Jan 14  SPHEREx

Edit February 1 UTC: It's B1075.17, skipping B1081.13.

https://www.spacex.com/launches/mission/?missionId=sl-11-4

SpaceX is targeting Saturday, February 1 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 3:02 p.m. PT, with backup opportunities available until 6:47 p.m. PT. If needed, additional launch opportunities are also available Sunday, February 2 starting at 2:29 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 17th flight for the first stage booster supporting this mission, which previously launched SDA-0A, SARah-2, Transporter-11, and 13 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.

Launching on B1075.17 at 23:02 UTC 1 February. PDF of online press kit and link to X livestream.

Weather Update:

Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1009 AM PST Sat Feb 1 2025

.SYNOPSIS...01/1008 AM.

A warming trend will continue through the weekend. Clouds will be
partly to mostly cloudy through Monday. The Central Coast will
have a chance of rain through Monday, mostly across SLO county. A
storm system will bring widespread rain and gusty winds Tuesday
through Thursday, and potentially into Friday with a small risk of
heavy rain.

&&

.SHORT TERM (TDY-MON)...01/1004 AM.

***UPDATE***

No changes to the forecast were needed for the mid-morning
update. A chance of light rain still exists for areas north of
Point Conception through early Monday morning, though most of
those areas will see well under 0.10 inches (if any at all), save
for the most northwestern tip of San Luis Obispo which may see up
to 0.50 inches. High temperatures today south of Point Conception
will be in the 60s-70s, while areas north of Point Conception
will be generally in the 60s, with the warmer areas just barely
hitting 70s thanks to cloud coverage preventing solar heating.
Gusty NW-W sub-advisory winds will affect the interior mountains
of Los Angeles and Ventura Counties, as well as the Santa Barbara
southwest coast. While the Santa Barbara southwest coast stations
reported just below advisory level gusts last night, there may
need to be a low-end wind advisory issued for that area for tonight.
As for the marine layer and low clouds, there is a higher chance
for a return of those low clouds tonight, but not expecting it to
be too impactful as of now.

Main focus/potential change today will be looking at the timing
of the upcoming system this week. While the current projected
amounts look to be on track with the current model data, the
recent GFS deterministic model run suggests two separate impulses
(peak rainfall). Periods of lighter rain may start as early as
late Monday morning (mainly up north), and potentially linger
through Friday. As for the timing of the impulses, one may occur
Tuesday night into Wednesday morning, and another potentially
Thursday afternoon into Friday.
