We use data from the coronagraph/polarimeter on the SMM spacecraft to examine the coronal streamers and coronal mass ejections (CMEs) associated with the appearance of the high-latitude, new-cycle active regions at the beginning of solar cycle 22 in 1986 and 1987. Short-lived active regions, those lasting less than a disk passage, were not associated with streamers or CMEs. CMEs were generally associated with a high-latitude region only when another strong active region lay within ∼30° of the longitude of the high-latitude region.
