Simultaneous ground and satellite observations of an isolated proton arc at subauroral latitudes
(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 ...
Time Evolution of the Substorm Current Wedge from Ground and Space-based Magnetic Fields
(2007-10-05)
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 ...
