MAGNETIC FIELD
Instruments Go Off Record
The Canterbury University physics department, which recorded a thousand-fold increase in red air glow aft r the nuclear test on Monday evening, reported other findings yesterday afternoon A micro-pulsation recorder which shows the very rap.d but small normal fluctuations in the earth’s magnetic field, was “saturated" just aflc the bomb went off. This means that tihe pulsations were so great that they went off the record. In Apia', Mr B Tinsleysenior Ph.D. student of tin physics department, used .. rheometer to measure Chang in the absorption of rad. . signals coming through t: ionosphere from outer span He reporfed absorption 10 times more than normal for a minute after the explosion then half an hour of increased radio noise, followed by slightly-increased absorption for two hours To measure intensity and Wave-lengths of the liy • produced by the bomb. M Tinsley used a spectograp: He had not developed tn plates when he reported bu’ said results should be good
Dr. C. D. Eliyett said th physics department was ex ceedingly grateful to th R.N.Z.A.F. for taking th
equipment to Western Sanaa it had provided very va able records.
