Quantifying the Size and Duration of a Microburst‐Producing Chorus Region on 5 December 2017
Geophysical Research Letters, 2022 Microbursts are impulsive (30 keV) precipitation (FIREBIRD II and AC6 CubeSats, POES) to determine the size of the microburst‐producing chorus source region beginning on 5 December 2017.

Relativistic electron precipitation
Geophysical Research Letters, 1979 Intense atmospheric bremsstrahlung X‐rays of energies ≳ 120 keV were detected by a balloon borne X‐ray experiment on September 30, 1976, flown from Fairbanks, Alaska. The X‐ray energy spectra have been obtained and compared to the primary electron energy spectra responsible for the X‐rays.

The Effect of Compression Induced Chorus Waves on 10–100 s eV Electron Precipitation
Geophysical Research Letters, 2023 On 7 January 2014, a solar storm erupted, which eventually compressed the Earth's magnetosphere leading to the generation of chorus waves. These waves enhanced local wave‐particle interactions and led to the precipitation of electrons from 10 s eV to 100

Auroral Ionosphere Model with PC Index as an Input
Atmosphere, 2022 Auroral Ionosphere Model (AIM-E) is designed to calculate chemical content in the high-latitude E region ionosphere and takes into account both the solar EUV radiation and the electron precipitation of magnetospheric origin.

Processes, microstructure and properties of vanadium microalloyed steels [PDF]
, 2009 Vanadium as an important alloying element in steels was initially associated with the properties achieved following tempering. Interest in the microstructure was stimulated by the advent of transmission electron microscopes with a resolution of ~1nm ...

Estimated nitric oxide density in auroras from ground-based photometric data
Solar-Terrestrial Physics, 2019 In this paper, we numerically estimate the nitric oxide density in auroras, using photometric data on 427.8, 557.7, and 630.0 nm emission intensities. The data were obtained at midnight at observatories of the Polar Geophysical Institute. These estimates
