Relationship of the Stable Auroral Red Arc Height to Solar Activity: Observation Results at the Yakutsk Meridian

First results of triangulation measurements of the height of stable auroral red arcs at the Yakutsk meridian in 2015–2020 are presented. Heights values of the lower luminosity boundary in arcs of 350–370 km near the maximum and 250–290 km during the minimum of solar activity in the 24th cycle are ob...

Description
Summary:First results of triangulation measurements of the height of stable auroral red arcs at the Yakutsk meridian in 2015–2020 are presented. Heights values of the lower luminosity boundary in arcs of 350–370 km near the maximum and 250–290 km during the minimum of solar activity in the 24th cycle are obtained. The reduced height of the red arcs in years of the minimum is due to a substantial decrease in the density of the upper neutral atmosphere.
