Optimization of Models
(University of Alberta, 1998)
The parameters of model auroral current systems were described in the previous chapter. To model the currents at any given time, these parameters must be adjusted to provide an optimal match to the available observations. ...
Workshop material about THEMIS
An Evening Sector Ps 6 - Omega Band Event
Abstract. Ps 6 magnetic disturbances and associated optical forms known as omega bands are usually associated with the morning sector. Some evidence for similar phenomenology in the evening sector has been presented ...
Athabasca University Initiatives Supporting THEMIS
Since the installation of a UCLA ‘small’ magnetometer in 1998, Athabasca University has made great strides in installing infrastructure in Canada for space science, culminating with the recent expansion of Athabasca ...
Automated Regional Modelling (ARM) for characterization of the substorm current wedge
Some characteristics of substorms may be determined through use of an electrojet forward modelling approach. These include the amplitude of cross-meridian electric current (0.2 to 1 MA typically), timescales (about 20 ...
Time Evolution of the Substorm Current Wedge from Ground and Space-based Magnetic Fields
Over the past several years, intensive efforts have resulted in a significant improvement in the ground instrumentation for auroral studies in North America. A major part of this is due to the THEMIS ground program, both ...
Inner solar system dynamical analogs for plutinos
By studying orbits of near-Earth asteroids potentially in 2:3 mean motion resonance with Earth, Venus, and Mars, we have found plutino analogs. We identify 23 objects in the inner solar system dynamically protected from ...
An Online Mechanics Experiment
Physics distance education has grown rapidly in recent years. The theory part of a physics course taught in this way has much common ground with other courses. However, lab instruction is an important part of introductory ...
Co-orbitals CASCA Talk
Presentation from CASCA 2006 covering general aspects of co-orbital motion with emphasis on the fact that they would be good targets for space missions.
