OCCURRENCE OF A SHORT-LIVED INCREASE IN RADIATION INTENSITY DETECTED ON AUGUST 20, 1960 IN THE SECOND SPUTNIK (in Russian)
Data obtained during the flight of the second Sputnik on an increase in the intensity of radiation due to charged particles are presented. This increase was noted on August 20, 1980, at 7 hours and 40 minutes world time. The detection instrument consisted of a telescope of two rows of gas-discharge counters with a geometry factor of 2.5 x 10/sup -4/ m sterad and a resolution time of 2 x 10/sup -5/ seconds. The increase was noted when the ship was in the northern hemisphere in the latitudes 50 to 60 deg . It was not registered at other times when the ship passed through approximately the same geographical region. It was therefore concluded that the rise in radiation was due to a flare of particles from the sun and not to traversal through a radiation belt. This conclusion was also supported by an increase in detection of particles with atomic numbers greater than five. The counting rate of particles with Z greater than 5 was found at this time to be 4.0 plus or minus 1.4 particles/minute as compared to an average count of 0.7 plus or minus 0.1 particles/minute. It is pointed out that the sun was active at the time of the flight of the second Sputnik and in fact a flare of intensity 2/sup +/ had died down just before the increase in radiation was noted. A chance coincidence of these two events has a probability of not more than 0.06. (TTT)
