Scientific paper

The Canadian Automated Meteor Observatory (CAMO) has been constructed to automatically observe meteors using image-intensified CCD systems to better understand the meteor ablation process, and to measure the daily meteoroid flux as well as mass and velocity distributions.
The system features both high spatial and temporal resolution, and can track meteors (down to magnitude 5.5) in real-time through a galvanometer system which keeps an 80 mm refractor telescope (1.5 degree field of view) directed at individual meteors. The tracking position is determined from a second camera with a 28 degree field of view. This gives a typical pixel scale of six metres, which permits a wide range of physical studies, including meteoroid fragmentation and high-precision deceleration. It also helps constrain system biases (such as the initial meteor trail radius effect) through direct comparions with other instruments, for example, the Canadian Meteor Orbit Radar (CMOR). Multiple observing stations separated by at least 50 km allow for the determination of heliocentric meteoroid orbits.
This work will present early results from this new system. Specifically, we will compare statistics of meteoroid fragmentation as a function of meteoroid orbit to help constrain the types of materials on these orbits. Implications of these comparisons will be discussed.
