This program continues studies of solar energetics and dynamics, based on the Mount Wilson solar tower observing facility and its digital database (dating back to 1967). The investigator's intent is increasing understanding of the solar cycle of variability and its influence on Earth's environment. In addition, he makes his data available to the community via the website. Specifically, this continuing program: (1) makes magnetogram observations consisting of magnetograms, dopplergrams and intensitygrams for at least 6 pairs of line wing samples in four different spectral lines, (2) applies an improved solar radius definition to the 1986-present data set, and (3) studies the vertical propagation of acoustic and magnetic oscillations using the sodium D line.

该方案以威尔逊山太阳塔观测设施及其数字数据库（可追溯到1967年）为基础，继续研究太阳能量学和动力学。 调查员的目的是增加对太阳变化周期及其对地球环境影响的了解。 此外，他还通过网站向社区提供他的数据。 具体地说，这个持续的计划：（1）在四个不同的谱线上对至少6对线翼样本进行磁图观测，包括磁图、多普勒图和强度图，（2）对1986年至今的数据集应用改进的太阳半径定义，（3）使用钠D线研究声振荡和磁振荡的垂直传播。
