Hearing from a source that SpaceX is now targeting March 4 for the launch of Transporter-10.

Starlink 7-16 likely follows Starlink 7-15, with a launch NET in the final days of February.  Starlink 7-15 is currently scheduled to launch February 22.  SpaceX is attempting ~four to ~five day turnarounds.

Assuming a successful February 22 UTC Falcon 9 launch, this launch would be NET February 26 or 27.  Transporter-10 follows on March 4, and appears to be a RTLS landing--OCISLY turnaround would not gate Starlink 7-16 with respect to Transporter-10.

Launch Time

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:
1063.17   Jan 24 Starlink 7-17
1075.10   Jan 29
1071.15   Feb 10

Edit March 4: Transporter-10 successfully launched March 4 UTC, using just-transported to Vandenberg B1081.5!

Edit March 11 UTC: B1063.17 launches Starlink 7-17.

Edit March 18: It's B1075.10.

Last night, NOAA forecast for Vandenberg at launch time was zero sky cover, winds diminishing, looked perfect.  This morning it is slight ran, thunder and 45% sky cover.    Anyone else seeing this?  I was going to hit the road in an hour, now I might hold.

SpaceX is targeting Monday, March 18 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 7:28 p.m. PT, with backup opportunities available until 11:10 p.m. PT. If needed, additional opportunities are also available on Tuesday, March 19 starting at 7:38 p.m. PT.

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

This is the 10th flight for the first stage booster supporting this mission, which previously launched SDA-0A, SARah-2, and seven Starlink missions. (=B1075-10) 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.

I was going to hit the road in an hour, now I might hold.

Checking just now, it looks like 25% sky coverage for most of the launch window. I generally don't drive up to see these things on work nights, but if this were a weekend launch, I'd go for it. Also worth noting that the launch window opens about 20 minutes after local sunset, so this flight has jellyfish potential. I'll probably be watching from the Redondo Beach pier. Good luck with the viewing (assuming you decided to go)!

Due to the persistent cut-off low over the lower desert creating winds from the east and driving moisture up from the Baja coast, some rather off-seasonal weather, especially thunder and hail has been showing up daily.  Here is the latest from NWS

Fantastic view from SoCal.  Great, bright plume.  Saw staging and could follow the 1st stage through entry burn.  Probably the best I've seen from here in OC.

BTW it looks all but certain to me that 2 out of 22 Starlink satellites on just-launched Group 7-16 are actually “Starshield” sats of the US military:
* Mysterious drop outs in live camera feeds from the 2nd stage during ascent
* No forward looking camera views seen as per usual practices
* CelesTrak only getting names of 20 satellites despite SpaceX saying 22 has launched
* This launch is targeting 306 x 316 km, somewhat higher than the 276 x 285 usually used for Group 7 launches lately. And despite this orbit insertion was at an astonishing low 138 km when recent Group 7 launches have SECO-1 at ~152 km high.

Galactic,

Great catch and explains the difference for this video.  Appreciate the deduction.

Maybe the two at the top of the stack are the Starshield and then an orbit adjustment later to place the Starlink to their proper orbit height?

🚨#BREAKING: Thousands of people are witnessing a spectacular jellyfish vapor across night sky

📌#LosAngeles | #California

Currently, across Southern California and into Arizona, millions are witnessing a spectacular event after SpaceX launched their Falcon 9 rocket from Vandenberg Air Force Base in California, producing a stunning jellyfish-like vapor trail. Some people are concerned, thinking it might be a nuclear warhead launching or even calling it a UFO, but it’s just SpaceX doing their thing.

🚨#UPDATE: More incredible footage shows the jellyfish  rocket vapor from the SpaceX Falcon 9 launch, as seen from Arizona.

Interestings. I wonder what Hartman's sources are that mean he thinks he can confirm.
It's possible; we'll see if appropriate catalog entries eventually appear. But I am not convinced yet.

Can someone help me with the math? I plug in 137 km altitude at 27361 km/hr to some equations and I get that it should be in an orbit of 137 km x -550 km orbit (that's negative, i.e. within the earth). Does SpaceX use earth's surface based numeric displays?

The quoted speed is Earth-relative, not inertial.

Edit: I estimate from the SupTLEs that SECO-1 was over 113W 26N more or less at an  azimuth of 141 deg. That means Vr = 27361 km/hr = 7.6003 km/s has components Vr cos (51 ) east, Vr sin (51) south.   Earth rotation vel is 0.4651 km/s at the equator, so 0.418 km/s east at 26N.   Adding these gives inertial velocity Vi = (4.783, 5.906) + (0.418, 0.000 ) = (5.201, -5.906)  which has norm  |Vi| = 7.869 km/s.

137 km perigee with Vi = 7.869  km/s at perigee results in a 137 x 297 km orbit.
A couple tweaks: taking into account the flattening of the Earth, this is actually only 134 km above the 'spherical fiducial Earth' which would give 134 x 287 km.
But: the result is VERY sensitive to the assumed latitude of the burn. If SECO-1
was at 22N instead of 26N, and that's a more realistic estimate when I model the orbit more carefully, the Vi increases to 7.883 km/s and the orbit is 134 x 334 km.  So there's a lot of slop given the uncertainties in the input data.

Earth-relative to where? The launch site? Do I need to do a 3D vector subtraction?

Relative to the rotating Earth surface, or more precisely to a coordinate frame rotating with the Earth.

USA 352 cataloged from NROL-123. Which leaves USA 350 and USA 351 unused. I presume these are reserved for the Starshields aboard this launch (which are not cataloged yet):

Quote
Space-Track has now cataloged the NROL-123 Electron launch. There are actually FOUR payloads:  "USA 352", MOLA,  Aerocube 16A and Aerocube 16B.  (Likely the earlier statement of 3 implies that AC-16A/B were deployed attached to each other and then separated?).
Quote
USA 352 is presumably an NRO payload. AC-16A/B are cubesats from the Aerospace Corporation. It is known that the Naval Postgrad School was developing a cubesat called Mola, so that's probably the other one.

https://twitter.com/planet4589/status/1771270082758426710

Edit to add:

Quote
The identification of the Electron payload 2024-053A as "USA 352" changes the balance of evidence on the Mar 19 Starlink Group 7-16 launch: it now seems likely that it DID carry two classified payloads, likely Starshield, to be designated USA 350 and USA 351 (59274/59275?)

This is a ground-based video, end-to-end, taken from San Diego (200 miles south of Vandenberg Space Force Base) and located about halfway through the second stage burn. From this vantage point, you can see from MECO, the booster and fairings following behind the second stage within the plume. Then, eventually, the booster continues on its ballistic trajectory right up to the entry burn. Although the video continues to the second engine cutoff (SECO), the landing burn is not visible as it is below the horizon.

In the second video, I edited a three-way with the SpaceX broadcast with two other videos. One video was taken from Santa Barbara and captured the Falcon 9 through the main engine cutoff (MECO) and a little beyond, and then we followed with the San Diego video. Enjoy!

With this first video advance to 1:05 to start viewing the F9.  The second video starts viewing from the beginning.

Some reusability stats for this launch (Starlink Group 7-16):

Booster B1075.10 turnaround time:
49 days 20 hours 31 minutes
(its previous mission was Starlink Group 7-12 on Jan 29, 2024 UTC).

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 52.08 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad SLC-4E turnaround time:
7 days 22 hours 19 minutes
(the previous launch from this pad was Starlink Group 7-17 on Mar 4, 2024 UTC).

FYI: median turnaround time for SLC-4E is currently 10.97 days *
* – based on the last 30 launches.

The same type of stats for previous SpaceX launches may be found on this spreadsheet (https://docs.google.com/spreadsheets/d/1WwD3CzpKR6vNgYS3QlxoOK9WLi81fof9zRiXzGCnbwo/edit?usp=sharing) online.
