Correlation of variations of explorer vi count rates with simultaneous visual auroras and high- altitude x-ray bursts
Study of dynamic morphology of polar aurora using all-sky-photography
Auroras and their excitation studied by injun iii
Spectrophotometric observations of emissions in aurorae and airglow
Visual observations of aurorae and summary of recorded emissions
Spectroelectrophotometry of nitrogen molecules, nitrogen ions, oxygen iodide, & nitrogen iodide emissions in aurorae
The X-radiation, occurring in the aurora zone, was first revealed in the summer of 1952 [1,2] rockets above 50 km. This radiation is mainly concentrated between the 62 and 77° geomagnetic latitude, with a maximum near 67.5°. It is generated at fast electron collisions with upper atmosphere particles.
Visual observations of aurorae from middle latitudes
Polar aurorae brightness related to geomagnetic field variation and short periodic pulsations of earth currents
Observations of Van Allen radiation regions by Explorer VI satellite - visual auroras, high altitude X-ray bursts, and simultaneous satellite observations during magnetic storms
Aurora and lower ionosphere in relation to satellite observations of electron precipitation
Direct observation of electron precipitation with rockets and satellites, showing that results agree with fluxes predicted from optical measurement of auroras
Dynamic motions of Aurora 7 towards equator
Visible and invisible aurora discussing morphology, occurrence, magnetic activity, absorption, geophysical and energy particle
Patches and irregular bands and eastward motions in morning sector of auroras
Equatorward motions of auroras
Diurnal and annual variations in atmospheric electric field intensity during polar aurorae
