DR. CHREE in his reply (NATURE, September 8, p. 361) to my communication on solar activity and atmospheric electricity (NATURE, August 11, p. 203) first makes reference to the status of the question as to the effect of sun-spot activity on the secular change of the earth's magnetism....
and Brice and Lucas; i.e., the plasmasphere fills during the storm recovery phase, preferentially on the dayside, and the intersection of the ring current with the increasing cold-plasma density of the plasmasphere results in the cyclotron instability when the stable trapping limit is reached. ...
Reexamining the question of a relation between the lunar-diurnal and the solar-diurnal variations, it was discovered that an abnormally large lunar-diurnal variation of Z existed at Amberley (New Zealand) during the night hours.doi:10.1029/JZ061i004p00748J. Egedal...
