An Early Mid-Latitude Aurora Observed by Rozier (Béziers, 1780) [PDF]
Annales Geophysicae, 2020 Aurora observations are an uncommon phenomenon at low and mid latitudes that, at the end of the 18th century, were not well known and understood. Low and mid geomagnetic latitude aurora observations provide information about episodes of intense solar ...

Solnečno-zemnaâ Fizika, 2018 We study the spatiotemporal dynamics of mid-latitude aurora from observations in the south of Eastern Siberia during St. Patrick’s severe geomagnetic storm on March 17, 2015. We perform a morphological analysis of characteristics of the observed auroras.

Auroras During Extreme Geomagnetic Storms: Some Features of Mid-Latitude Aurora on February 11, 1958
Solnečno-zemnaâ FizikaThis paper discusses peculiarities of the great mid-latitude aurora that occurred during the extreme magnetic storm on February 11, 1958. This mid-latitude aurora had unusual optical and spectral characteristics, among which, first of all, were very high

A rare observation from mid-latitude of a blue aurora
Journal of Space Weather and Space ClimateAurora observations at mid-latitudes are rare but not exceptional. The aurorae are usually seen as diffuse red illuminations of the sky above the Northern (respectively Southern) horizon (respectively in the northern and southern hemispheres) because ...

MID-LATITUDE AURORA IN SOLAR CYCLES 23–24 FROM OBSERVATIONS IN THE SOUTH OF EASTERN SIBERIA
Solar-Terrestrial Physics, 2019 The paper presents observations of mid-latitude aurora (MA) in the south of Eastern Siberia in solar cycles 23–24. Spectral composition and dominant emissions of MA, daily distribution of MA detection probability, dependence on the level of geomagnetic ...

Geophysical Research LettersAbstractMid‐latitude auroras are conventionally generated during intense magnetic storms. However, mid‐latitude auroras were observed by naked eyes at Beijing China (39°N, 116°E) unusually during a moderate storm event on 1 December 2023 with the minimum Sym‐H index only −120 nT. This study combines conjugative in‐site and ground‐based observations to

A possible case of sporadic aurora observed at Rio de Janeiro
Earth, Planets and Space, 2020 Being footprints of major magnetic storms and hence major solar eruptions, mid- to low-latitude aurorae have been one of the pathways to understand solar–terrestrial environments.
