On the correlation of meteors with micropulsations

Abstract

Nighttime geomagnetic micropulsations were observed in the 1.5-cps frequency band down to a limiting sensitivity of 0.05 m,),. These results were compared with all-sky and localized radar meteor rates obtained at the same site to investigate the magnetic effects pro duced by meteors. The variation of meteor rates for each hour, plotted through a succession of nights, is not significantly related to the corresponding micropulsation activity. Individual meteor occurrence has been examined by recording on the same chart as the micropulsation activity. Most individual meteors do not have any associated micropulsation activity, but the number of coincidences is greater than random, and it remains possible that some of the larger meteors do produce magnetic effects .
