    • Inner solar system dynamical analogs for plutinos 

      Connors, Martin; Stacey, R. Greg; Brasser, Ramon; Wiegert, Paul (2006-08-18)
      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 ...
    • Inner solar system dynamical analogs of plutinos 

      Connors, Martin; Stacey, R. Greg; Wiegert, Paul; Brasser, Ramon (2007-11-20)
      By studying orbits of asteroids potentially in 3:2 exterior mean motion resonance with Earth, Venus, and Mars, we have found plutino analogs. We identify at least 27 objects in the inner solar system dynamically protected ...
    • Interpretation of Automated Forward Modeling Parameters for Sawtooth Events and Substorms 

      Connors, Martin; McPherron, Robert L.; Clauer, C. Robert (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 ...
    • Introduction 

      Connors, Martin (1998)
      Introduction on solar-terrestrial interaction.
    • linfit code 

      Connors, Martin (2006-07-05)
      Linear fit to an arbitrarily long 2-column dataset.
    • May 25, 2007 Meteor 

      Connors, Martin (Please contact Martin Connors for more information: martinc@athabascau.ca, 2007-05-31)
      The file shows a view of the whole sky on Friday May 25 at 1:07:20 am with data from 1:07:24 superposed. This shows the meteor track in the southern sky, inside the box near the bottom along with the start point just ...
    • Noctilucent Cloud Videos, Jun 23 2006 

      Shelton, Ian; Dalin, Peter; Connors, Martin; Zalcik, Mark (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 One-meter Robotic Telescope for Western Canada 

      Martin, Brian; Connors, Martin (2008-10-11)
      1-m class telescopes are arguably the workhorses of modern astronomy and represent an excellent return of science for a relatively modest capital investment. Such instruments can be used in large-field survey work, ...
    • An Online Mechanics Experiment 

      Connors, Martin; Bredeson, Christy (2006-09-30)
      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 ...
    • Onsets and Flapping Studied Using a Dynamic Harris Sheet Model 

      Connors, Martin; Lerner, Rob; Gaugey, Geraldine; Lavraud, Benoit; Volwerk, Martin; McPherron, Robert L. (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 ...
    • Optimization of Models 

      Connors, Martin (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. ...
    • Physical Parameters of Substorms from Automated Forward Modeling 

      Connors, Martin; Ponto, Jason; McPherron, Robert L. (2006-07-08)
      AFM technique applied to give average parameters of substorms and relation to AL index, Weimer parametrization, optical data
    • Physical Processes 

      Connors, Martin (1998)
      Physical processes in near-Earth space with attention to ground and satellite magnetic fields.
    • DE Pictures 

      McMullin, Blaise (2006-07-10)
      Photos of remote labs and DE student.
    • Progress on Low-Cost Pulse-Counting Magnetometers for Geomagnetic Studies 

      Connors, Martin (2007-11-28)
      "what the world needs now is a good $500 magnetometer"
    • Simultaneous ground and satellite observations of an isolated proton arc at subauroral latitudes 

      Sakaguchi, Kaori; Shiokawa, Kazuo; Ieda, Aki; Miyoshi, Y; Otsuka, Y; Ogawa, T; Connors, Martin; Donovan, Eric F.; Rich, F. J. (Journal of Geophysical Research, 2007)
      We observed an isolated proton arc at the Athabasca station MLAT: 62◦N) in Canada on 5 September, 2005, using a ground-based allsky imager at wavelengths of 557.7 nm, 630.0 nm, and 486.1 nm (Hβ). This arc is similar to ...
    • Space Physics: Aurora Borealis 

      Jaugey, Geraldine (2007-08-13)
      Cluster data was used to examine the magnetospheric boundary and more particularly the tail. Harris sheet fits were done in a dynamic fashion that allows flapping to be quantified.
    • STEP Forward 2007-2007 Space Science Enhancement Proposal to CSA 

      Connors, Martin (2006-05-19)
      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 ...
    • A Survey of Orbits of Co-orbitals of Jupiter 

      Stacey, R. Greg; Connors, Martin; Brasser, Ramon (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 ...

      Stacey, R. Greg; Connors, Martin; Brasser, Ramon (2006-05-25)
      Co- 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 was discovered ...
