The technique of data adaptive filtering is used to identify Pi 2's concealed by the presence of typical daytime Pc type pulsations. Convincing new evidence is presented demonstrating that Pi 2 pulsations occur simultaneously in both the nightside and dayside hemispheres at low latitudes. Dayside Pi 2's are occasionally identified at mid latitudes. These results have implications with regard to the source mechanism for low latitude Pi 2 pulsations and allude to a global cavity mode.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1382825895769917824","@type":"Researcher","foaf:name":[{"@value":"Peter R.
