Impact during lunar eclipse

[Metryq]

So, is there any seismological evidence that this was a meteoroid impact during the recent lunar eclipse, or is it simply assumed? I know the EU position is that craters in the Solar system are a mix of EDM and impact, but I was thinking that an impact during the eclipse was coincidental. If EDM, then perhaps not so coincidental, as the flux across the lunar surface was changing at the time.

Since labs have spent millions of dollars shooting objects into various materials at hyper velocites in a fain attempt at understanding crater formation. I would think this moon flash recording science program would at least try to correlate some of these flashes with actual pictures of the moon surface. In order to help science understand what we are seeing.

They claim to deduce the 'mass' of all these objects which created the flashes, but I doubt that very much. In fact, n rocky object impacting another rocky object, in the Dark Vacuuumm of Space, no matter what the velocity, will NEVER produce a flash. I am very certain of that, if I ignore any plasma or electric properties. But I don't own a lab to test that, so I guess I really can't prove it.

Piezoelectricity is the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter such as bone, DNA and various proteins)[1] in response to applied mechanical stress.

This is why Wintergreen flavor Life Savers flash when you chew them (in the dark).

What luck that all these rocks hitting the moon are some sort of crystal ceramic bone dna life savers.

Sarcasm duly noted. Do you agree or disagree? EU proponents regularly express the concept that EM forces are the same in an earthly laboratory as when scaled up to universe proportions. Scale up from the speck of crystal that when struck generates the piezoelectric ignition spark in a butane lighter.

Yes, my apologies for the snark, but let's get back to science then. I have found this an interesting investigation now.

I found a paper linked by universetoday.com which provides some data points. It could be said, that there are 70,000 flash events on the Moon every year. They are extremely short in duration, 33 to 165ms. With the new dual-band NEOLIANT, they've mathed out temperatures. And from "the first ten [flashes] they detected, they obtained temperature estimates ranging from about 1,300 to 2,800 °C ( 2372 to 5072 °F)." This is approaching Red Star levels. The 'coldest' of know Stars, iirc.

They estimate as well the impactor mass to be a 100g to 55kg. This 1 mag higher then previous estimates. Speed of the impactor is basically an unknown and could be anywhere from a slow to hyper. Such is the difficulty when deducing things from a few pixels of a picture.

So of course, we only see flashes. We don't see what caused the flash, or what's leftover on the surface afterward. However if the Moon as received over a million impacts the last couple decades, I would love to see a time-lapse of the crater morphing that must be going on.

So where does the flash we are measuring come from. The paper only refers to this.
"Pioneering laboratory experiments were conducted more than 40 years ago, using dust accelerators and photomultipliers with filters at several wavelengths, allowing the estimation of the plasma temperature (Eichhorn 1975, 1976; Burchell et al. 1996a,b)."

Emphasis of course all me, because that surely makes a difference I think. As would a charged object moving through dusty space snapping tiny rocky insects out of the vacuum in a flash of light. spiz, snap, sizzle.

Don't get me wrong, of course impact craters occur, but I don't believe these flashes are from kinetic only impacts. Maybe I'm wrong. Until we get more then a few pixels of light, it's going to be hard to tell unless someone goes up there and get's a GoPro of it.

I read somewhere that the laser reflector left by Apollo is the only ALSEP still functioning. If there were any working seismometers, I would expect some correlating evidence if the flashes are impacts. I suppose even an EDM event might register, but then the mainstream astronomers will be telling us the impactor was "less dense than water." A styrofoam cup impacted with such force that it registered a flash visible from Earth! Maybe it was dark matter!

I can't wait for the Chinese to record a picture/video from the cold dark side of the Moon. Apparently the 'dark' side has more 'impacts' then the Earth side. So they said in a recent news story about how they recorded the coldest every temperature during the 14-day Moon Night, some -300+F.
