Spatial distribution of Pi2 micropulsations

摘要: Abstract Investigations of Pi2 micropulsations show that one can obtain very good correlations over distances about 1000 km in the North-South direction between geomagnetic latitudes 62°30′N and 54°20′N, yet much poorer 140 km. These differences km, which are particularly marked vertical component, may be associated with coastline or geological effects.
