Method for Studying Twilight Phenomena

  • V. G. Fesenkov


Many papers have been devoted to the investigation of twilight phenomena, but they have been mainly of a descriptive nature. Conclusions about the optical properties of the upper atmosphere, which, it would seem, should be the principal goal of twilight research, are usually drawn in a highly elementary manner, on the basis of rather arbitrary simplifying assumptions. The optical properties of twilight are incomparably more complex than those of the daytime sky.
