A Thor IRBM was used to launch a Mk 4 Reentry Vehicle containing a 186 kg W-50 nuclear warhead of either 200 or 400 kilotons yield. The detonation occurred at an altitude of 98 km, 69 km SSW of Johnston Atoll, and resulted in dramatic aurora-like effects visible as far away as Hawaii. More notably, the explosion had a massive effect on the ionosphere which disrupted radio communications over the entire central Pacific for three hours.
