oa MNASSA : Monthly Notes of the Astronomical Society of South Africa - The light of the night sky

 

Abstract

The blackout has made us very conscious of the light of the night sky. On clear moonless nights, the light coming from the sky is quite sufficient to enable us to see the outline of such things as trees, houses, etc., or even of the mountains miles away. On cloudy nights, on the other hand, the limit of visibility is practically reduced to zero.
