Optical Signatures of the Outer Radiation Belt Boundary

open access: yesGeophysical Research Letters, 2019
We present observations that show structured diffuse aurora (SDA) correlated with electron precipitation directly from the outer boundary of the outer radiation belt.

Sporadic Aurora near Geomagnetic Equator: In the Philippines, on 27 October 1856 [PDF]

open access: yes, 2018
While low latitude auroral displays are normally considered to be a manifestation of magnetic storms of considerable size, Silverman (2003, JGR, 108, A4) reported numerous "sporadic auroras" which appear locally at relatively low magnetic latitudes ...

Upward, MeV‐Class Electron Beams Over Jupiter's Main Aurora

open access: yesGeophysical Research Letters
Jupiter's poleward (Zone II) main aurora exhibits bi‐directional electron acceleration; upward acceleration dominates but downward acceleration generates strong aurora.

Observation of O+ 4P-4D0 lines in proton aurora over Svalbard [PDF]

open access: yes, 2004
Spectra of a proton aurora event show lines of O+ 4P-4D0 multiplet (4639–4696 Å) enhanced relative to the N2 +1N(0,2) compared to normal electron aurora. Conjugate satellite particle measurements are used as input to electron and proton transport models,

The Aurora radiation-hydrodynamical simulations of reionization: calibration and first results [PDF]

open access: yes, 2016
We introduce a new suite of radiation-hydrodynamical simulations of galaxy formation and reionization called Aurora. The Aurora simulations make use of a spatially adaptive radiative transfer technique that lets us accurately capture the small-scale ...

Portuguese eyewitness accounts of the great space weather event of 1582

open access: yesJournal of Space Weather and Space Climate, 2020
Newly discovered descriptions about the great aurora observed in March 1582 are presented in this work. These records were made by Portuguese observers from Lisbon. Both records described the aurora like a great fire in the northern part of the sky.

Study of plasmasphere dynamics using incoherent scatter data from Chatanika, Alaska radar facility [PDF]

open access: yes
Results of the study of Chatanika incoherent scatter radar data and Lockheed Palo Alto Research Laboratory satellite data are reported. Specific topics covered include: determination of the effective recombination coefficient in the auroral E region ...

The Influence of the Stretch of Mini‐Magnetospheres Formed by Crustal Fields on the Martian Bow Shock Location

open access: yesGeophysical Research Letters
Mars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the ...
