Connexion between Micropulsations and the Ionosphere


DUFFUS has recently pointed out a connexion between P c occurrence and the F-region1. Other workers2 have found correlation between P t and f 0 F 2 and it can reasonably be asserted that the ionosphere is a major factor in the transmission path by which these characteristic geomagnetic micropulsations are observed at ground-level. Recent work here has offered some further evidence on this subject.
