Abstract: | In order to further observing programs aimed at the possible meteor storms of November 1998 and 1999, we describe here how the Leonid shower is expected to manifest itself on the sky. We discuss: 1) the expected wavelength dependence of meteor (train) emission, 2) the meteor brightness distribution and influx, 3) the stream cross section, radiant and altitude of the meteors, 4) the apparent fluxes at various positions in the sky as a function of radiant elevation as well as 5) the trail length and radial velocity, and 6) the diameter and brightness of persistent trains as a function of radiant elevation. These topics were chosen to help researchers plan an observing strategy for imaging, spectroscopy, and LIDAR observations. Some applications are discussed. This revised version was published online in July 2006 with corrections to the Cover Date. |
