As at Guam, marked and continuing F2-layer irregularities were
found in the records taken at Maui following the three largest shots

ed natural occurrence of similar disturbances,
there ‘seems to be
little doubt that these were shot-caused effects.
The velocity of
travel is wceertain since the time of onset of the disturbance is not
well determined. Prior to the period of marked perturbation following each of Shots 1, 2, and 5, there were indications of the possible
arrival of the disturbance about 5 hr after the shot. This doubtful
arrival is indicated in Table 3.4 as "First Period (doubtful)", Also
included in Table 3.4 are data for Shot Mike effects, Pound upon ree

one being in the period 15 April to 15 May.
