Greetings,
Hands down, meteorites are cold when they land :-)
Apollo Astronauts reported the smell of gun powder from the moon dust.
Perhaps many bodies in the solar system have that smell. Falling
through the atmosphere should remove the regolith though, except where

I was under the impression that it's a myth that direct friction from O and
N molecules on the surface of a meteorite create the heat that causes
ablation.

Hi,
Ursula Marvin has attributed many of the reports of hot stones with a
sulphurous smell to a "fire and brimstone" expectation on the part of the
observers, especially for the older historic falls. She notes that the
reports of hot stones still exist - primarily due to what observers think

Greetings listees,
ahhh the hot/cold debate rears it's head again. I appreciate Bernd's
list of falls that seem to indicate warm more so than cold but there
are many factors to consider when compiling data. In Bernd's list, how
many of these warm specimens were observed by laymen?? Often there
Thanks Bernd.
From your data we have as score:
"warm": 14 versus "hot": 8
I believe this can be completed by browsing through other archives or
accounts of some recent witnessed falls ?
Are there data reporting "cold, frozen or alike" meteorites ?
Take care,

Are there ANY photos of any meteorite, taken *immediately* after it

I know some people have reported meteorites as warm, (e.g. Peekskill).

I don't think there is a general answer to that question. It depends heavily
on the size of the body after ablation. The larger it is, the longer it will
take to cool down as it falls for a few minutes through cold (around -40°C)
air. So a large body will be closer to the temperature it was at i
