Fig. 19 — Noise at New Soutligatc, Eiiglaiul, in January — Wiriation with exposure 

 of equatorial belt to sunlight 



point docs not roniiilftely control the rise and fall of liie iiigii night- 

 time static. It has been foniul that the discrepancy can be accounted 

 for if sunrise and sunset are .taken with respect to a static transmission 

 path as distinKuished from the receiving point alone, and if the as- 

 sumption is made that the effect of sunliglit upon the static trans- 

 mission path is similar to that on usual radio transmission.
