Eos, Transactions American Geophysical Union, 1973 The polar aurora is perhaps the most fascinating and mysterious of the many spectacles that Nature puts up for us to observe. Only direct observation can reveal its three‐dimensional grandeur, but some of the beauty can be captured in color photographs such as those included with this article (taken by Gustav Lamprecht of College, Alaska).

Space weather with an arc’s ∼2 h trip across the nightside polar cap
Frontiers in Astronomy and Space SciencesFlow channels can extend across the polar cap from the dayside to the nightside auroral oval, where they lead to localized reconnection and auroral oval disturbances.

Photometric Studies of Auroral Luminosity and its Connection with Some Atmosphere Ionization Phenomena [PDF]
, 1958 The auroral radiation, 3914 AO, received from the entire sky on a horizontal diffusing plate was monitored continuously during the nights of 1955-56 and 1956-57. The 1955-56 data and part of the 1956-57 data were used to obtain a diurnal curve for the

Effect of the NO concentration on the ratio I₅₅₇.₇/I₄₂₇.₈ in auroras
Solar-Terrestrial PhysicsWe have examined the effect of the nitrogen oxide concentration on the ratio between λ557.7 nm and λ427.8 nm emission intensities in auroras caused by precipitating electron fluxes, using the numerical simulation method.

Field‐Aligned Currents Induced by Magnetopause Motions Under Pressure Perturbations
Geophysical Research LettersIn this work, we identified 65 auroral arcs that stretched out from the equatorward boundary of auroral oval with azimuthal extensions, and investigated their upstream triggering, by utilizing conjunctions between the THEMIS probes and the all‐sky ...
