This section showcases a few snapshots digitized from the body of footage obtained during field-trips to the CANOPUS Rabbit Lake site by Wollaston Lake, Saskatchewan, March 1994, 1995, and 1997. A schematic drawing and photograph of the instrument setup has also been released, along with a few public relations viewgraphs. All images below, except those under the heading `Ultra Thin Arcs', were obtained using a Nikon 105 mm f/1.8 lens. See also the viewgraph illustrating the imager's field of view. The field of view in each image is about 13.5 by 10.1 km at auroral heights (~105 km altitude). North is up and west is to the right, a natural orientation when looking up antiparallel to a magnetic field line while aiming your camera (the camera optical axis was aligned to the local magnetic field line). Integration time was 1/60th second. No optical filtering was performed. Pseudo-colors have been added in some cases to aid in discerning small scale features. Images are thus mainly of scientific interest. For more information regarding these images, cf. the most recent scientific publications. NOTE: The Movie Clips below are hopelessly outdated. New, longer movies using QuickTime technology available upon request. NOTE: Please have a look at some Kelvin Helmholtz phenomena at Patrick Witting's site. Do these remind you about some of the below images? Pretty fundamental stuff, in other words.... Still Images Movie Clips (MPEG) Auroral `Curls' Linear structures (320 kb) [grayscale] Auroral `Coronas' Coronas (30 kb) [looped][colored] Black Auroral Vortices Curls (40 kb) [looped][colored] Ultra Thin Arcs (~ 10 m) Black Curls (16 kb) [grayscale] Very Thin Arcs (~ 100 m) Black Patch (114 kb) [grayscale] Thin Arcs (~ 1000 m)

Both spatial and temporal resolution have been dramatically decreased so as to minimize the size of the MPEG encoded files. The frame-rate you experience will depend on your particular mpeg viewer and computer system. You may have to step through the sequence of frames manually if things flash by too quickly.

You may not use these images for scientific and/or commercial purposes without our written permission, as all images, whether stills or time-series, are © 1994, 1995 by the ISR (I suppose). We wish to thank the Canadian Space Agency (CSA) for kind permission to use the Rabbit Lake CANOPUS facility.
