Research on Leonid MAC:

Light Curves, Satellite Impact Hazard issue

In an observing effort executed by Ian Murray,and in collaboration with Bob Hawkes of Mount Allison University, we have used dual coaxial microchannel plate image intensified monochrome CCD detectors run at standard NTSC frame rates (30 fps) to study the Leonid meteor shower during the 1998 and 1999 Leonid MAC missions. In the 1999 Leonid MAC, we discovered that the lightcurves tended to differ from those in the 1998 campaign, suggesting that meteoroids fragmented differently. In future missions, we will continue to study the morphological changes as a function of different positions in the comet dust trails and as a function of age since ejection.
