Rob, All,
Absolutely agree re: Dirk, and that's an interesting analysis of those
videos (both in the link and in your comments). Does the apparent speed
appear to be a bit "hot" as well?
All the best,
Dave

Hi Count,

I absolutely concur that Dirk's efforts seem to be appreciated by many, but
publicly acknowledged by few. So let me go on record thanking Dirk for his
tireless efforts -- more often than not, he is the first to report on a new
potential meteorite-dropping event, and his site is a must-visit for seeing
early videos.

Unfortunately, I'm of the opinion that the San Luis Potosi videos are an
elaborate hoax, as the meteor cannot be confirmed using one of my reliable
sources. There was no bright meteor over central Mexico at any time from 4
pm to 6 pm local time (CDT) on 21 August, which corresponds to 21:00-23:00
UT.

Apparently I'm not the only one of this opinion. Dirk forwarded me the
following link that he received from someone who has picked apart the four
videos. You can judge for yourself, but I think he/she has found some subtle
"glitches" and oversights that call into question their validity:

I am also bothered by the mismatch between the reported time of the fall
(~5:25 pm) and the sun's elevation angle -- particularly in the church
video. The sun appears to be very high in the sky for so late in the day.
And where are all the witness reports, or stories in Mexican newspapers?

Finally, two of the videos are too "lucky", in the sense that they just
happened to be recording something rather un-video-worthy (some random train
from a car, and a poorly framed church tower) and the meteor magically
appears.

What do you all think? --Rob

Hi Listers,

One of the small things in life, but something that brings big pleasure is
to have the opportunity to compliment and thank someone for their providing
free gratis excitement and interest into your life.

Our colleague and friend in Tokyo, Dirk Ross, tirelessly maintains his WORLD
WIDE METEOR/METEORITE site gathering and posting the news,videos and photos
of events we are interested in.

His posting of the four extraordinary videos of the August 21st. meteor
crossing the mountains and valleys near San Luis Potosi, Mexico are
thrilling. The last of the four is such a classic that it will always remain
in my memory bank. It is far more interesting than the video of the Great
Fireball of 1972 (Gran Teton Grazer.)

Thank you Dirk..I understand there were sonics associated with this meteor.
It would be great to find if it became a meteorite.

Cordially,

Count Deiro
