(meteorobs) [Bulk] Re: Question on an interesting meteor -Another Model.

[Larry]

Hi all,

An interesting aspect here is that depending on the angle of travel relative 
to the photographer..... This meteoroid could be "Tumbling" instead of 
having rotation around its axis of travel. Clockwise tumbling as viewed from 
the nearside.

Tumbling of an irregular object would have the same appearance as we see 
here photographically and might better explain the short (upper) periodic 
outgassing.
