Abstract : A cloud, illuminated by the rays of the sun, shines as a result of res nance fl orescence by which it can be observed from the earth's surface. In this experiment, the sodium vapors were released at 430 m above the earth's surface. During the experiment, the height of the earth's shadow was 300 km. The bservations lasted 15 minutes, and abo t 50 cloud photographs were obtained. At this time, the cloud reached dimensions of hundreds of ilometers. Since each sodium atom experiences a great number of collisions with atmospheric atoms, a diffusion distribution is established in the cloud for a short time interval after the sodium vapor is released (we can show that t is time is 1 0 sec nds).
