An investigation is made of the simultaneous emission of X-ray and UV photons as a function of time and location in the auroral oval, and comparisons are made of their time variations with the intensity variations of Auroral Kilometric Radiation (AKR

The Polar Ionospheric X-ray Imaging Experiment (PIXIE) on board the NASA/GGS POLAR spacecraft has been making observations of ionospheric X-ray emissions from the vantage of space for more than 3 years. A wide variety of observations have been made b

An examination is made of a large body of auroral X ray and auroral kilometric radiation (AKR) data acquired on the Polar satellite in order to investigate the relationship between these two phenomena on a global scale. A detailed study was made of 1

Most photons detected by PIXIE (the X-ray imager aboard GGS/Polar and the first instrument to provide global X-ray images of Earth) have resulted from precipitation of auroral electrons. Here we trace magnetic field lines (from the high-latitude iono

The Polar Ionospheric X-ray Imaging Experiment (PIXIE) on NASA's POLAR spacecraft has been making global observations of X-rays from the Earth's auroral regions since March, 1996. PIXIE is a remote-sensing global monitor of multi-keV electrons which

Since AKR is believed to be generated by anisotropic electron distributions on auroral field lines, it is important to investigate the correlations of AKR with precipitating electrons. At present little is known about the corresponding variations for
