Abstract:

On 12 September 1959, at installation Comet A two cameras, objective diameter 100 mm, f500 and f250, 28 frames were obtained showing an artificial comet sodium cloud ejected from the second Soviet cosmic rocket. Both cameras photographed simultaneously starting at 21h 35m 00s Moscow time. The times of the beginning and end of the exposures are given of the last five pairs of photographs. The photographs contained 6 images of the sodium cloud obtained with the f250 camera and one with the f500 camera. The first photograph, in the form of a bright star with a weak aureole, was obtained on frame No. 10 both cameras. In subsequent photographs the cloud emerged in the form of an expanding ring with irregular brightness distribution. The maximum blackening density was observed in a direction close to that of the movement of the rocket. Author
