Abstract
THROUGH measurements at the Pic-du-Midi, Garrigue1found that the average intensity of the yellow line in the night sky 10° above the horizon is about 2.8 times that at the zenith, from which Cabannes, Dufay and Gauzit2 found the altitude of the layer emitting the yellow line to be about 130 km.
