B1059.4 can be seen still at Lz1. They have attached the cap, but the legs I can see are still down. #SpaceXFleet #SpaceX

Falcon-9 deorbit burn possibly observed last night over Pennsylvania

•I have not posted here for a long time but am now as I think I just got to see the deorbit burn or fuel depletion for the rocket that launched SAOCOM1B. I was not looking for it but was sitting on my front porch here in Lebanon PA USA and in the NNW I saw this light about like a airplane landing lights but an unusual area of lighted cloud around it. Soon the "headlight“ went out but the cloud continued. It was only about 10 degrees above the horizon. It moved into the west were it basically became invisible. It appeared to be a retrograde orbit. I thought of a deorbit burn but that did not hold out as I did not know how one would occur there. I checked things out and find out that this was the first sun synchronous launch from FL in decades. So I think that is what I saw and hope to see more! I attached a photo I got though it is not very good but it still gives you an idea what I saw. The lower right is where the rocket burn occurred but higher and left was more "cloud" that was moving along with it. [add] I did not note the exact time but it was somewhere around 00:50 on August 31 UTC.

Jim O adds: Falcon9 deorbit burns can be spectacular:

Will anybody be doing a composite video(side by side of the groundtrack as it progresses and an onboard video from S2.....Also is there any more vid from the source showing the ground view of fairing sep(it cut out quickly after sep).

Did I missed something or there were no static fire before this launch?

Correct, there was no static fire for this launch and this week Starlink launch won't have one either. Something new they're doing that they already tested with B1059.3 couple months ago.

Some views of the Falcon 2nd stage firing seen from the Caribbean. Video description (google translate):
The Argentine satellite Saocom 1B, which took off yesterday from Cape Canaveral, in the United States, aboard a rocket from Space-X, surprised and in some cases alarmed the inhabitants of Santo Domingo and other cities in the Dominican Republic and Puerto Rico, surprised with the sighting of a "flying object" that was documented in home videos that circulated profusely on social networks.

A dozen reports have now come in, with videos and photos, of the observation of a deorbit burn over NW Ontario 80 minutes after launch.

eg,

from the poster: "This is what I saw last night @ approx 8:54pm. I posted this on a few replies on this forum already and I am honestly perplexed by this entire situation. Looking at who saw this in Ontario, it seems like other witnesses saw this exact same object. People from North Bay, Gravenhurst, and St. Catherines saw this. This draws a possible straight line between North Bay and St. Catherines - Right down the Hwy 11 S corridor. There's more description on my YouTube vid. My mind is blown. This was a very interesting experience. If anyone has an answer to what this could be, I welcome it!

I made a side by side video stream views from just before launch to the First Stage landing. Enjoy.

Ms. Chief finally pinged and will be back at Port Canaveral in less than an hour. #SpaceXFleet #SpaceX

Ms. Chief returns to Port Canaveral with two fairing halves that she scooped from the water and they appear to be intact. #SpaceXFleet #SpaceX #SAOCOM1B

What's the estimated altitude at the time of the deorbit burn? And where was the NOTAMS impact zone?

GO Ms. Chief arrived at Port Canaveral overnight with her solo fishing haul from #SAOCOM1B. This marks the first mission a catcher has scooped both fairing halves. The crane has arrived to remove them and chances are high they will go out for Starlink NET 9/3.

Deployment orbit was just over 600km circular

Has there been any chatter about the sonic booms? The reentry was heard in my neighborhood 40 miles inland, which was outside any of the graphics that I'd seen posted. There were also some images showing a focused boom from the ascent being onshore. I haven't seen anything in media covering the launch so far.

Edit: Found one
https://www.fox35orlando.com/news/literally-shook-our-house-residents-across-central-florida-hear-sonic-boom-after-successful-spacex-launch

This is really interesting.
What is the red track in that map?
Is it the old predicted ground path, like onespeed showed, or the IIP path?

The map has an intense sidelobe far inland near Frostproof, FL.
(edit: The sound footprint comes from the Environmental Assessment page 78. It is for the return of the first stage.)

There is another map, posted on "The Talk of Titusville" that has the inland sidelobe near Basinger, some 60 km to the southeast of Frostproof.
(It comes from page 76 of the attached Environmental Impact Statement. It is for the launch.)

Are there any known observations from the ground in either of these sparely populated areas?

This post referenced something about a 0.025 square kilometer area of intense overpressure on the barrier island near Vero Beach.
It was an unpopulated spot, but someone may have been there, too.
Any known reports?

edit: Replaced second map with clip from Environmental Impact Analysis
