So I noticed at about 1:11:30, right after SECO2, there appeared to be an inside-the-fuel-tank shot, just for a moment. I don't recall having seen this previously. Anyone else?  You think this was RP1 or LOX?

There was a discussion about this a couple pages back.
Doh. I searched the thread for keywords but came up empty. I'll scrounge more thoroughly. Thanks!

Short answer: it's the LOX tank. It's been seen multiple times before. It's an engineering camera feed that isn't "supposed" to be on the webcast but it does no real harm to see it. LOX is light blue in color and RP-1 is dyed red to comply with US federal tax regulations, so we know it's not RP-1 (undyed kerosene is clear).

Space-Track has produced 100 new placeholder entries.

Next step: We have 118 Objects in orbit, 2021-006A to -DD.

Inclinations 97.51° ± 0.01
Apogee 531-538 km
Perigee 513-529 km

118 - 4 Starlink rods - 1 rocket stage + 20 on ION = 133. Ten satellites not registered so far.

I've watched every launch and don't recall having seen this before. Can you point to any other videos featuring it? It's plausible that if it were only a few frames I might have always looked away at just the wrong time... thanks!

Almost into the final orbit, nice!

Starship, Vulcan and Ariane 6 have all reached orbit.  New Glenn, well we are waiting!

Cargo ship Morning Train is blocking our view from Fleetcam right now, but I checked in to see how B1058 looked from a different angle. We've got 2 legs up and 2 legs down.

Thanks for snagging the frame from the LOX cam.  I missed that despite always looking for it.
Aviators99:  That used to be shown on every mission.  SpaceX used to broadcast that as the engine shut down and the LOX went from this condition, with a choppy surface, to smooth floating blobs.  Now we just see a frame or two on some flights.

The landed first stage appears to be left leaning.
Possibly a nod to being close to Cuba? ;)

If I recall correctly it used to show up quite often in the early F9 launches, if you watch the first bunch you should see a few.

Falcon 9 Core B1058 just went horizontal at Port Canaveral with all four legs stowed, as seen by @NASASpaceflight Fleetcam.

Payloads identified so far:

4 of 5 Astrocast
35 of 48 Flock
3 of 3 Hawk
2x ICEYE
7 of 8 Lemur
24 of 36 Spacebee
10 of 10 Starlink
GHGSat C2
XR-1
ION
38 unassigned objects
---
126 total

8 Flock and 12 Spacebee are still on ION. There should be 148 objects overall (143 sats + 4 Starlink rods + 1 rocket stage), so there are 2 items still not detected.

XR-1 = ICEYE seems to be confirmed. IDs are also similar, ICEYE X9 is 2021-006CX and XR-1 is 2021-006CY.

New objects identified since 7 February:

- the 5th of 5 Astrocast
- Charlie
- 3 Flocks, now 38 of 48 detected
- 4 of 8 Kepler
- QPS-SAR Izanami

and 3 more unidentified objects detected (EG, EH and EJ). Looks like one of the Flocks had already been released from ION by February 7; else there would be one item too much in space now.

I forgot the ESPA stack, which was jetisonned before Starlink deployment. The identified Doves so far have all very similar orbits, and they have these numbers:

- Flock 4s 1-9, 11-13, 15-40

Obviously Flock 4s 1-40 are those deployed directly, and 41-48 went with ION. This means #10 and #14 are still hiding, and the ION deployments were not detected so far.

There's one in the CRS-4 webcast back in 2014, if you can still replay this one.  Here is a whole youtube video highlighting this camera view.   Shorter shots have been shown on many missions since.

LOL, this question was from two weeks ago, but thank you for this much longer view.  FYI Lou you can suppress NSF's auto-embed behavior (that messed your post) by removing the leading "www." from Youtube URLs.  I did this in the quote above and now we can read what you wrote :)
PSA #1:  Suppress forum auto-embed of Youtube videos by deleting leading 'www.' (four characters) in YT URL; useful when linking text to YT, or just to avoid bloat.
PSA #2:  Users who particularly annoy you can be suppressed in forum view via Modify Profile -> Buddies / Ignore List.  *** See profile for two more NSF forum tips. ***

And the last of the Doves has taken off. @planetlabs thank you for flying ION, we hope you had a pleasant flight and we look forward to welcoming you again onboard our ION Satellite Carriers.

...we need to start thinking about some frequent flyer program...#pulse #ion @D_Orbit

A few more satellites have been identified since 11 February:

- CubeL (PIXL)
- 1 Flock, now 39 of 48 detected
- Hiber 4
- 8th of 8 Lemurs
- Yusat 1

Now 136 objects detected, 28 of which are unidentified. Presumably 12 Spacebees still on ION and the last Dove not yet detected, to give a total of 149.

Next batch of satellites identified:

- 9 Flocks, now alll 48 of 48 detected
- 8th of 8 Kepler

136 objects detected, 18 of which are still unidentified. Assuming 12 Spacebees still on ION, this makes 148 total an 1 object missing.

Unidentified:

- 3x ARCE, ASELSat, IDEASSat, Prometheus 2-10, PTD-1 (Elana 35), SOMP2b, UVSQ-Sat, 3x V-R3x
- Sherpa FX
- F9 upper stage, ESPA stack, 4x Starlink rod

Next batch indentified:

- IDEASSat
- PTD-1 (Elana 35)
- UVSQ-Sat
- Prometheus 2-10

14 unidentified objects left, 1 object still missing, assuming 12 Spacebee on Ion.

Just wondering if anyone knows what happened to the 12 Spacebees that were on board ION MK02? The mission updates (https://www.dorbit.space/mission-updates-pulse) show the successful deployment of the 8 Superdoves, and now says it is onto IOD/IOV of ARGO and DRAGO with no mention of the Spacebees.

They should still be in the ION vehicle.  I don't know when they will be deployed.

11 objects left unidentified, which seem to be:
5x debris
Sherpa-FX
3x V-R3x cubesats
ASELSAT
SOMP2b

(plus the 12 SpaceBees still need to be deployed from ION)
