Leonid MAC 1999


An unusual image of an "elve" captured by M.J. Taylor and L.C. Gardner of the Space Dynamics Lab., Utah State University, during the night of the Leonids storm at 02:10:00 UT.

This airglow image by M.J. Taylor and L.C. Gardner shows regular and chaotic structure in the upper atmospheric OH nightglow emission layer (altitude ~87 km).

Joe Kristl and Mike Taylor of Space Dynamics Lab. present a sequence of images of a near infrared meteor observed with the NRL InGaAs camera flown on the FISTA aircraft.

This images shows the spectrum of a bright afterglow by Jiri Borovicka. Another afterglow spectrum was obtained by Peter Jenniskens/Mike Wilson. The meteor was imaged from ARIA and occured at 04:00:29 UT.

NASA/Ames Astrobiology Academy student Matt Lacey, currently at Stanford University, took this unusual spectrum of a persistent train (raw data) of a not quite so bright Leonid at 03:34:12 UT, some tens of seconds after the train formed.
