BTW, our other local incident this week: Shiny white and dark sphere hovered stationary over Carlsbad State Beach, California "Shiny white and dark sphere" also known as the Goodyear Blimp seen face-on.

Source: r/sandiego post "any idea what this is ?" A commenter on the water said it was 2 parachutists landing on the USS Midway, each with 2 flares. Skydiving Innovations, the demo team that jumps onto the Midway, confirmed by email to me...

Thanks, great clip. It's a second, separate recording from the homeowner's, filmed the night of Feb 15. Same tone: 1147 Hz, steady within about half a Hz from 0:17 to 0:24, harmonics up to the 7th. The first 9 seconds show the pitch rise really...

I agree, just mentioning it for the next "UFO at a Volcano" video , I've seen a number of them that appeared to be drones. This one I agree is a launch.

Good tip, thanks. I don't think it fits this one, though. The clouds spread out and glow the way a vent does, they show up right when and where the stage's orbit puts it (due south of the camera at 19:24), and they vanish when it enters Earth's...

In plain terms: a Chinese rocket's upper stage, about 50 minutes after launch, was still in sunlight high up while the ground was dark, and the glowing cloud around it looks like leftover fuel being vented. Argentina saw it first, then a Mexican...

@Mendel thanks, noted, I'll quote from now on. Your quote has the key line too: Dawes said no pitch increase could be heard at the end. In the TV clips there is one, two of the stops chirp up 8-13 Hz. @jon_eir fair question. Checking whether the...

Happy Saturday all. Follow-up on the original Kiev clip: I think the sound was real :) and came from building or paving work beside the filmer's block, not a hoax or a sample. I can't name the machine, and some of this is soft, so I've flagged...

Turns out this was mostly worked out back in 2016, it just never got around. An audio engineer, Langston Holland, sent Andrew Dawes (the Pacific U physicist who mapped the reports) an analysis matching it to a copper tube ringing on a defective...

Could it be something like a change in aperture, as seen in flautists' pitch bending? Source: https://www.youtube.com/watch?v=Yd-CGxKJnyQ The funny thing about that is that the change demonstrated might be considered counterintuitive if you...

@jon_eir checked. No shaft-rate line near 57 Hz in any of the four clips (TV audio often cuts the low end, so that alone isn't much), no ~57 Hz sidebands around the tone, and the loudness doesn't pulse at shaft rate. It hits full volume in about...

The use of "rotating" is interestingly reminiscent of the old "racetrack ufos" back when starlink flares first caught our attention, if you interpret "rotating" as "going around in circles."

The directionality of the microphone doesn't help much if the sound is already sufficiently loud, unless your technique is to identify the dropouts at 120⁰ that should give a fairly narrow angle. A better technique might be to use two...

Starlink flares would have been visible at the time

Perhaps the good old Starlink? It might be a bit too bright though (compared to the foreground). But I also know todays phones are great. Ps, the article is one of those typical "we know what we saw" ones.
