Observing the Mid-Latitude Aurora

Light in Nature VII, 2019
The aurora is a beautiful night sky optical phenomenon that is readily seen at high-latitude locations, but with more effort can also be seen and enjoyed at mid-latitude locations. Guidelines for when and where to look are presented, along with a rich array of photographic examples of mid-latitude auroras exhibiting all the usual range of green, red ...

Initial Phase of Mid-Latitude Aurora During Strong Geomagnetic Storms

Advances in Space Research, 2008
Abstract Analysing the initial mid-latitude aurora phase during strong geomagnetic storms we found that the initial phase of the mid-latitude aurorae observed at 630 nm emission during the strong geomagnetic storms on March 24, 1991, April 6, 2000, October 30 and November 20, 2003 is characterized by a short (∼1 h) wave-like disturbance.

Post-Storm Mid-Latitude Green Aurora and Electron Precipitation

Planetary and Space Science, 1981
Unusual auroral emission at mid-latitudes, showing nearly exclusively the green oxygen line (557.7 nm) and occurring during the early part of the recovery phase after strong magnetic storms is described. The emission has a life-time of up to several hours, consists of cloud-like patches and appears quite isolated at medium latitudes with no ...

Geomagnetic and Ionospheric Disturbances Associated With Mid-Latitude Auroras on March 17, 2015

25th International Symposium on Atmospheric and Ocean Optics: Atmospheric Physics, 2019
We carried out comparative analysis of the ionospheric, optic and geomagnetic disturbances observed during night hours of the main phase of the 17–18 March magnetic storm in the East Asian sector. It has been revealed that synchronous peaks of 557.7 and 630.0 nm emission intensity were associated with substorm-like enhancements of the westward ...

Evolution of the Mid-Latitude Red Aurora Over Northern China During the 5 November 2023 Geomagnetic Storm

Journal of Geophysical Research: Space Physics
Abstract This study presents novel observations of a mid‐latitude red aurora event at 44°MLAT over Northern China during the 5 November 2023 geomagnetic storm, using simultaneous observations from ground‐based instruments (630 nm all‐sky imager (ASI) and ionosonde) at Mohe station (53.5°N, 122.4°E; MLAT = 44.32°N) and space‐based ...
