Re: [meteorite-list] Meteorite Picture of the Day: Alais?

2018-02-22 Thread Katsu OHTSUKA via Meteorite-list

Thanks for a nice picture.
But, the texture of this meteorite looks not CI1 but CM or CR.
So, the meteorite may be not Alais (CI1) but Al Rais (CR2-an)?
But, I don't know whether or not the Paris museum houses a collection of Al 
Rais.

Subject: Re: [meteorite-list] New fall, Nkayi Zimbabwe

Last week I noted that there were 9 instances of two meteorite falls 
occurring on the same day since 1865.  I found my data on these so here they 
are:


1. Aug. 25, 1865 - Aumale, Algeria (L6) and Shergotty, India (Martian)
2. Aug. 28, 1925 - Ellemeet, Netherlands (Diogenite) and Lanzenkirchen, 
Austria (L4)
3. Aug. 8, 1933 - Sioux County, USA (Eucrite) and Repeev Khuyor, Russia 
(Iron)

4. Sept. 17, 1945 - Atoka, USA (L6) and Soroti, Uganda (Iron)
5. Sept. 21, 1949 - Akaba, Jordon (L6) and Beddgeler, Wales (H5)
6. Oct. 20, 1951 - Manych, Russia (LL3.4) and Yambo, Congo (H5)
7. Oct. 30, 1994 - Devri-Khera, India (L6) and Lohawat, India (Howardite)
8. June 21, 2002 - Kilabo, Nigeria (LL6) and Thuathe, Lesotho (H4/5)
9. March 1, 2009 - Carterville, USA (chondrite) and Nkayi, Zimbabwe (L6)

Additionally, in two instances, falls occurred on the same day but in the 
same area, and are assumed to be from the same fall. They are:


Sept. 26, 1939 - Glabggang, Indonesia (H5/6) and Selakopi, Indonesia (H5) 
Both fell near Bandung
Nov. 13, 1952 - Galim (a), Cameroon (LL6) and Galim(b), Cameroon 
(EH3/4-an)Rubble Pile??


Enjoy,

Frank

Hello List,
If you are looking for the same day but different years then you can
use this service.
It is a bit outdated statistic based on MetBase data. MetBase has a
day of fall/find and MetBull doesn't. That's why not all the recent
falls are listed. But still you can play with this to see how many
falls/finds where recovered the particular day. Just choose the day
and check: http://sv-meteorites.com/play_with_statistic.aspx Best regards,

half after the Repeev Khutor iron landed just north of the Caspian Sea.  I 
think Kilabo and Thuathe fell about 5 hours apart. Cheers, Frank On Friday,

Thank you Linton, Thank You Michael.
And yes, Michael, you are right, that PDF version is illegal and has
now been reported to Springer.

Yes, neither author lived long enough to enjoy the result of their
work. In fact, Larry Chitwood died the very day the book was finished;
he had spent most of the day working with Richard and Dorothy Norton,
then decided to take a walk before dinner, and he was later found on a
hiking trail, apparently victim of a massive heart attack. Richard was
seriously affected by that death and did not last very long after that.

Thank you for supporting that excellent book, and yes the 2 widows do
get a (small) royalty check.
Right now that book is very hard to find but it is (or will shortly) be
re-printed, and Dorothy and I still hope very much to have available
during the Tucson show.

Any questions, just ask!
