Abstract : This report contains a summary of EG&G fireball photography and a preliminary analysis of the results for Shot Tanana of Operation Dominic. Tanana, an LRL-sponsored device, was detonated on 25 May 1962, at GZ-10, southwest of Christmas Island. Measured time of drogue-retarded fall from the B-52 delivery aircraft, flying at an altitude of 25,000 feet, was 50.853 seconds. The device was detonated at an altitude of 9,030 ft +/- 50 ft above MSL. The local Christmas Island time of detonation was 0708:50.7922, uncorrected for WWVH propagation time. Phi scaling indicates a fireball yield of 2.3 kt +/- 0.3 kt, and Mach scaling shows a yield of 2.4 kt +/- 0.4 kt.
