This RUI project will investigate aspects of the coronal heating problem through mapping temperature of the solar corona and studying the oscillation spectrum of coronal loops during the low-background circumstances of an eclipse. Observations provide tests of proposed mechanisms to explain the heating of the solar corona via weakly compressive magnetohydrodynamic waves. The 26 February 1998 total solar eclipse will provide more and brighter loops because of the rising phase of the solar activity cycle. These new observations will greatly improve previously published results, as well as distinguish between standing and propagating waves.

这一RUI项目将通过绘制日冕温度图和研究日食低背景情况下日冕环的振荡谱来调查日冕加热问题的各个方面。 观测提供了测试的建议机制来解释加热的太阳日冕通过弱压缩磁流体动力学波。 1998年2月26日的日全食将提供更多和更明亮的环，因为太阳活动周期的上升阶段。 这些新的观测结果将大大改善以前发表的结果，并区分驻波和传播波。
