[meteorite-list] Most confirmed falls in a year?

[Matson, Rob D. [US-US]]

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

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?

In addition to the 17 witnessed falls worldwide for 1933, that year also had two others that are possible falls, Elton, Texas and Willard (b) New Mexico.

1933 has the record with 17. 1949 had 13 and 1950, 76 and 98 all with 12.

Hi Listees,

I was recently wondering, what year has the most confirmed witnessed falls?

I have been closely following falls since the year 2000, and according
to my records we have a few contenders in recent years. I am thinking
one of these must be the most.

2018 has 15 falls, but two of them are not official (HaH 346, aka
Ghadamis, was classified as a find) and a fall over Pakistan was not
recovered or recorded. This leaves 14 classified falls in a 12 month
period :

Jan 05, 2018 - Matarka (L6 chondrite) : Morocco
Jan 16, 2018 - Hamburg (H4 chondrite) : Michigan USA
Feb 16, 2018 - Ablaketka (H5 chondrite) : Kazakhstan
Apr 19, 2018 - Aba Panu (L3.6 chondrite) : Nigeria

Jul 26, 2018 - Glendale (L6 chondrite) : Arizona USA
July 27, 2018 - Benenitra (L6 chondrite) : Madagascar
Aug 12-17?, 2018 - "Bhakkar" (unofficial) (ordinary chondrite?) : Pakistan
Aug 21, 2018 - Gueltat Zemmour (L4 chondrite) : Morocco
Aug 26, 2018 - Hammadah al Hamra 346 (L6 chondrite) : Libya (aka "Ghadamis")
Sep 26, 2018 - Komaki (L6 chondrite) : Japan (Hammer)
Oct 28, 2018 - Ksar El Goraane (H5 chondrite) : Morocco
Dec 23, 2018 - Mhabes el Hamra (H4/5 chondrite) : Mauritania

2020 gave us Covid-19 and 13 classified falls :

Jan 01, 2020 - Cavezzo (L5-an chondrite) : Italy
Jan 09, 2020 - Zhob (H3-4 chondrite) : Pakistan (Hammer)
