Shot Wrangell was a 1500-foot balloon shot sponsored by LRL and detonated on 22 October 1958 in Area B-Fa of the Nevada Test Site at 0850 PST. The fireball yield was 6. 3 tons 5. 0 tons. Photographic coverage of fireball growth was provided by four high-speed Eastman cameras, two each at Station P-362 6 x 6 No. 2 and Station F-369 6 x 6 No. 3. In addition, two Rapatronic cameras were located at each of these stations to record early fireball growth. Three Eastman cameras and three Rapatronics provided good records. The remaining Eastman and Rapatronic, because of malfunctions, did not provide records suftable for analysis. The Station locations, together with the burst location, are shown in Figure 1. Figure 2 contains the Survey Data.
