This paper describes the coordinated results of several sets of measurements of two Leonid meteor fireballs over northern New Mexico at 1:32 and 3:06 MST respectively on the night of 17 November 1998. The measurements included visible band photometry on both events, as well as filtered 5890-Angstrom all-sky images of the sodium airglow. Also, for the 3:06 AM event we obtained an infrasound measurement of the hydrodynamic yield. For the 1:32 AM event we obtained a set visible band CCD camera images of the meteor train for times extending to 30 minutes after the initial impact. The measurement results have been combined to derive an optical efficiency for the intense early-time optical flash, and the total explosion yields and masses for both of the meteors. We have also done a set of numerical radiation, hydrodynamic, and chemistry computations to investigate the nature and distribution of the longlasting airglow. We attribute the brightest visible airglow to atomic oxygen 5577-Angstrom line emission, with additional contributions from atomic sodium emission and NO2 chemiluminescence. The near-infrared atmospheric bands of molecular O 2 should be very strong as well. All of the band emissions are expected to show a hollow limb-brightened structure.
