Abstract

The High Resolution Telescope and Spectrograph was flown on the Spacelab-2 shuttle mission to perform extended observations of the solar chromosphere and transition zone at high spatial and temporal resolution. Ultraviolet spectroheliograms show the temporal development of macrospicules at the solar limb. The C IV transition zone emission is produced in discrete emission elements that must be composed of exceedingly fine (less than 70 kilometers) subresolution structures.

摘要

高分辨率望远镜和光谱仪搭载在航天飞机-2 号任务中，以高空间和时间分辨率对太阳色球层和过渡区进行扩展观测。紫外分光日像仪显示了日边缘大日珥的时间演化。CIV 过渡区发射是由离散的发射元产生的，这些发射元必须由极其细小（小于 70 公里）的亚分辨率结构组成。
