CLOUDS HIGHLIGHTED BY FLASH. This photo- 

 graph, like the others in this group, was taken 

 from a distance of about 15 miles from the bomb 

 detonation point. From a photographic standpoint 

 Able Day was excellent, with bright sunshine and 

 few clouds. The clouds shown in these pictures 



were at an altitude of two or three thousand feet, 

 or considerably higher than the altitude of the 

 bomb itself at the moment of explosion. At sea 

 level there was brilliant sunlight. Comparison of 

 positions of clouds shown in these views suggests 

 the relative position of the cameras.
