Equatorial Enhancement of Micropulsation pi-2
Yanagihara, K. & Shimizu, N.
Abstract
 Equatorial enhancement of micropulsation pi-2 is found clearly by the use of rapid-run magnetogram during the IGY.
The diurnal variation and latitudinal dependency of the enhancement is similar to those of the other kinds of disturbance.
A possible cause of the enhancement is discussed.
