Coronal Transients at High Heliographic Latitudes

Abstract

One of the few properties of coronal transients to have been demonstrated to show a variation which may depend on the phase of the solar cycle is their distribution with latitude. Observations from Skylab (1973–74) showed a distribution which was restricted largely to the region between 45 ° N and 45 °S. Data from the the Solar Maximum Mission, on the other hand show transients over a much wider range of latitudes. A spacecraft at high heliographic latitude near the time of solar maximum is thus likely to encounter coronal transients directed towards it and because of its trajectory, offers a more favorable opportunity to identify the interplanetary signature of these events than is found near earth or in the ecliptic.
