RUI: Coronal Heating Studies at the 1991 Eclipse

太阳日冕的加热将通过观测 7月11日日全食日冕振荡谱 1991.这将是一个非常有利的日食方面， 持续时间和可能的观看条件。的意见 提供了一个机制的测试，以解释太阳能加热 通过阿尔芬波的电晕。 加热发生在该地区 太阳风的形成。 拟议中的新实验 改进了1980年和1983年日食期间的先前观测结果 通过改进全食期间的图像采集， 的频率范围内观察，通过大大提高 跟踪，并通过改进的数字化技术， 数据记录本科生将积极参与 在仪器的开发、测试和观测中， 这项研究的活动。***//

Heating of the solar corona will be studied by observing the coronal oscillation spectrum at the total eclipse of 11 July 1991. This will be an extremely favorable eclipse in terms of duration and probable viewing conditions. The observations provide a test of a mechanism to explain the heating of the solar corona via Alfven waves. The heating takes place in the region of formation of the solar wind. The proposed new experiment improves on prior observations during eclipses of 1980 and 1983 by improved image acquisition during totality, a major expansion of the frequency range under observation through greatly improved tracking, and through improved techniques of digitization and data recording. Undergraduate students will be actively involved in both the instrument development, testing, and observation activities of this research. ***//
