[meteorite-list] Cutting space rocks in CA
In anticipation of blowing the dust off my lapidary saw to cut a few meteorites (it's been years since I last used it), I knew I would need to pick up some more denatured alcohol. So I popped into Home Depot, and to my surprise (or maybe not, in retrospect) they no longer sell it in CA because it's apparently been banned in this state. A little research suggests it was banned in CA a few years ago (probably for completely ridiculous reasons). So the question: what liquid do you Californians (and Canadians) now use to cut your meteorites? Isopropyl is still legal, so I suppose I could go that route. I'm pretty sure camp stove fuel is just ethanol (with a bitterant added) -- perhaps that can still be purchased in CA? --Rob __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist2.pair.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Very sad news
R.I.P. to John Blennert -- I met him once or possibly twice over the last quarter century, so knew of his considerable prowess hunting gold (via metal detecting) as well as meteorites, on this continent and others.

[meteorite-list] Meteorites from 2024 BX1
Congratulations on your finds, Zsolt! A little back-story from my end. I followed 2024 BX1 from the moment of its discovery (having been fortunate enough to be at my computer when I got the first JPL/SCOUT alerts). After the first 7 observations, the minor planet community knew it was going to be an impactor in northern Germany in less than a couple hours (21 Jan 2024 00:32:45 UT). As the # of telescopic observations grew from 7 to 20 to 50 to over 100, I kept adjusting the impact trajectory, ultimately constraining the terminal path to about 100-meter uncertainty. Meanwhile, I grabbed the radiosonde upper atmospheric wind data launched from Lindenberg (only 110 km away from the future fall location) and ran dark flight predictions. This is the first fall where I was able to generate a map of predicted mass locations ... BEFORE the meteoroid even hit the atmosphere! I passed this map and kmz file on to Peter Jenniskens who was flying out the next day. (Also a few others who had expressed interest in searching for fragments of this Apollo asteroid.) As Zsolt knows, this was no run-of-the-mill fall. In a fresh fall (such as the one that occurred north of Quartzsite, AZ at the end of December), the stones are almost always covered in black fusion crust -- usually a matte black for chondrites, or a shiny, glassy black for many types of achondrites. Not so for this new fall north of Brandenberg! If I had been over their searching, I could easily have walked right past these newly arrived rocks from space that to the casual eye look like terrestrial stones. Hats off to (I believe) the Polish team that made the first 3 or 4 finds, recognizing them for what they were! 2024 BX1 was not a large meteoroid: between 0.8 and 1.4 meters in size, depending on its albedo. The orbit is (or rather was) well established, with an aphelion that pretty much ruled out a (low albedo) carbonaceous chondrite. So the size was most likely around a meter or slightly less. The entry velocity was relatively slow (15.2 km/sec), but the entry angle was quite steep (only 15 degrees from vertical). The former favored meteorites on the ground, while the latter still meant the total recovered mass would be low. Anyway, kudos again on your rare finds, Zsolt! And a big shout out to Hungarian astronomer Krisztian Sarneczky for finding and rapidly reporting 2024 BX1! This was not Krisztian's first rodeo -- he has the unique distinction of having discovered not just one Earth impactor, but now THREE! (Less than a year ago he discovered 2023 CX1 -- the asteroid that entered over Normandy and was also successfully found by meteorite hunters.) Clearly he is doing something right with his setup and operational plan!

Re: [meteorite-list] Most confirmed falls in a year?
Hi Mark – in 1933, people spent more time outdoors than they do today (and, probably less important, they enjoyed much darker night skies). I expect that the annual rate of meteorite-producing falls has remained about constant over the last century, with year-to-year variations consistent with Poisson statistics. With improved technology (weather satellites, all-sky cameras, dashcams, ring cameras, Doppler radar, etc.), the odds of successful recovery of a given witnessed fall improves, but that factor may not be enough to counter the (likely) decrease in witnessed events (particularly daytime events). Remember that bolides with the greatest chance of producing rocks on the ground fall between local noon and midnight – from meteoroids that are “catching” up to the earth from behind and thus have slower average entry velocities than those occurring between midnight and noon. In the 1930s, a greater fraction of the population were outdoors from 8 am to 8 pm – a 12-hour time window when 64% of meteorite falls occur (based on Met. Bulletin data from 1860-2017). Of course, there are a lot more people in 2023 than in 1933, but most of those outdoors during the day are likely driving or staring at their phones (or both). --Rob From: Meteorite-list On Behalf Of Mark Lyon via Meteorite-list Sent: Monday, March 20, 2023 7:29 AM To: Frank Cressy Cc: Finbarr Connolly ; Meteorite List Subject: EXTERNAL: Re: [meteorite-list] Most confirmed falls in a year? That's surprising that there would be a record in 1933. I figured new technology, rising populations, and an increase in meteorite hunters would mean that there were more witnessed falls more recently than 90 years ago. Have the number of witnessed falls per year tended to be significantly higher more recently or has it stayed about the same?

I will put in my guess and say the first meteorite(s) were found a half mile south of Bourville. For light masses (10-30 grams), I’d put it further west-northwest, a half-mile south of Ermenouville.

Radar signatures appear in higher elevations of the KMTX 1428 radar data set. They are mostly visible in the Velocity data because the radar is nearby and there is interference from ground clutter and weather. They appear roughly parallel to and north of I-80 along a track that approximately matches both the AMS ground track and GLM signatures. The ground track of these radar signatures is long, but that appears to match GLM data showing a low entry angle, fairly long ground track. I see signatures consistent with fast-moving meteorites in five radar sweeps (between 4 and 12.4 degree sweeps). Videos of this event show a fast moving, bright daytime fireball. I'm surprised to see radar signatures given the apparent speed, but they appear reasonable for a meteorite fall.
