The Height Distribution of the Kinetic Temperature and Turbulent Velocity of Solar Hα Spicules
Abstract
The height distribution of the kinetic temperature of solar Hα spicules is determined using the widths of optically thin hydrogen and metallic lines obtained at the total solar eclipse of 1966: the temperature was found to be 8600 K at the height of 2200 km measured from the radial optical depth of unity at 5000 Å, and to decrease to a minimum of 5000 K ± 180 K at 3200 km, and to increase again to 8200 K at 6000 km.
