Night sky at Athabasca with Athabasca University Robotic Telescope in foreground.
Onsets and Flapping Studied Using a Dynamic Harris Sheet Model
(2007-10-31)
We have developed a nonlinear fitting routine for the Harris current sheet based on magnetic data, and applied it to 71 plasma sheet crossings by Cluster. In most cases this simple fit appeared to represent the magnetic ...

Linear fit to an arbitrarily long 2-column dataset.
Interpretation of Automated Forward Modeling Parameters for Sawtooth Events and Substorms
(International Conference on Substorms 8, 2006)
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 ...
Noctilucent Cloud Videos, Jun 23 2006
(2006-07-23)
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 ...
A Survey of Orbits of Co-orbitals of Jupiter
(2006-06-29)
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 ...
Cross Meridian Currents in Storms and Sawtooth Events
(2006-11-17)
Automated Forward Modeling (AFM) is an inversion technique based on magnetic data alone, which can indicate physical parameters associated with electrojets and field-aligned currents. From perturbations along a meridian, ...
