太阳峰年使命飞行任务航天器上的可见光波长日冕仪/偏振计正在提供关于日冕瞬变所表现的耀斑过程的数据和关于太阳活动周期目前阶段演化日冕中断程度的数据。我们的第一个结果是发现了频繁的H.阿尔法帽。外日冕爆发性射电遗迹的发射和首次观测到的3.2R/太阳下Fe XIV谱线发射。在瞬变的早期阶段，偶尔会发现比周围日冕密度小的空洞尾随瞬变环，环相对较厚且无结构。在52天的观测的初始调查中，已经确定了大约22个瞬变;从这个样本中，我们的初步结论是，SMM时代（接近太阳活动极大期）的瞬变发生在比Skylab时代（接近太阳活动极小期）的瞬变更宽的纬度范围内，但速度范围大致相同。
The visible wavelength Coronagraph/Polarimeter on the Solar Maximum Mission (SMM) spacecraft is providing data on the flare processes manifested by coronal transients and on the degree of disruption of the evolutionary corona at the present epoch of the solar activity cycle. Among our first results are the discovery of frequent H..cap alpha.. emission from remnants of eruptive prominences in the outer corona and first observations of Fe XIV line emisson to 3.2 R/sub sun/. In the early stages of transients, cavities less dense than the ambient corona are occasionally found trailing the transient loops, with the loops being relatively thick and structureless. Some 22 transients have been identified in the initial survey of 52 days of observations; from this sample our preliminary conclusion is that transients during the SMM era (near solar maximum) occur over a wider range of latitude than, but with about the same range of speeds as, transients during the Skylab era (near solar minimum).
