В геофизической литературе активно обсуждается гипотеза о том, что поверхностные волны на магнитопаузе могли бы быть источником дневных широкополосных пульсаций диапазона Pc5-6 (~1-2 мГц) на околокасповых широтах. Однако первые попытки найти наземный отклик на эти колебания не дали обнадеживающих результатов. Так, сопоставление дневной границы открытых и замкнутых силовых линий (т. н. OCB - Open-Closed field line Boundary) по данным радара SuperDARN с пространственной структурой Pc5-6 пульсаций, зарегистрированных на сети магнитометров на околокасповых широтах, показало, что спектральная мощность этих пульсаций имеет максимум преимущественно на 2-3° более внутренних оболочках магнитосферы, чем положение OCB. Дополнительно связь между OCB и геомагнитными пульсациями исследована путем сопоставления профиля мощности дневных пульсаций с экваториальной границей аврорального овала, определяемой по красной кислородной эмиссии по данным сканирующего фотометра на Свалбарде. В большинстве проанализированных событий «эпицентр» мощности Pc5-6 пульсаций оказался примерно на 1-2° более низкой широте, чем OCB, определенной по оптическим данным...
