Abstract
We presented the first results of triangulation measurements of the stable auroral red arcs height at the Yakutsk meridian in 2015–2020. The heights 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 decrease of the red arcs height in the minimum years is due to the significant density decrease of the upper neutral atmosphere.
