Jupiter’s Trojan asteroids fulfill the prediction of Lagrange that orbits can be stable when a small body orbits in specific locations relative to its ‘parent’ planet and the Sun. The first such Trojan asteroid was discovered ...

Photos showing AU attendees at CASCA 2006, held in Calgary in early June 2006.

Photos of remote labs and DE student.

The most effective way to exploit Canada’s ideal position for auroral zone science is to emplace instruments with sufficient density for meaningful studies. Magnetometers are useful instruments for this since their cost ...

Spacecraft traversing the auroral oval respond primarily to the field-aligned currents at its poleward and equatorward borders that are part of a solenoidal current system. If electric and magnetic field measurements are ...

Automated Forward Modeling (AFM) is an inversion technique based on magnetic data alone, which can indicate physical parameters associated with electrojets. From perturbations along a meridian, the total electric current ...

Linear fit to an arbitrarily long 2-column dataset.

Videos of noctilucent clouds (NLC) seen from Athabasca University Geophysical Observatory on June 23 2006. NLC are mesospheric clouds which are very high and lit up by the sun despite it being well below the horizon at the ...
