The authors propose to use new submillimeter and millimeter observations of the Sun from the James Clerk Maxwell Telescope (JCMT) to model the low and middle chromospheres of sunspots and magnetic flux tubes in plage. This program will be a continuation of an exploratory solar program they recently completed to open the JCMT to solar research. Under this program, the JCMT gave the authors the first submillimeter observations of the chromospheric supergranular network, of sunspots, and of prominences, opening these fundamental solar phenomena to the powerful LTE diagnostic tools of the far infrared continuum. The new program will be based primarily on analysis of the large amount of high-quality data already obtained. However, further observations will also be made on the JCMT. These will include the development of improved mapping techniques, observations at longer wavelengths (out to 2 mm) and observations of intensity variations due to oscillations and possibly fares, using SCUBA, the 100 element bolometer array under development at the JCMT. The new program will also include preliminary analysis of observations of the total solar eclipse of 1991 July 11 over Mauna Kea.

作者建议利用詹姆斯·克拉克·麦克斯韦望远镜 (JCMT) 对太阳的新亚毫米和毫米观测来模拟太阳黑子的低色球层和中色球层以及海滩中的磁通量管。该计划将是他们最近完成的探索性太阳能计划的延续，该计划旨在向 JCMT 开放太阳能研究。在该计划下，JCMT 为作者提供了对色球超颗粒网络、太阳黑子和日珥的首次亚毫米观测，为远红外连续谱的强大 LTE 诊断工具打开了这些基本太阳现象的大门。新计划将主要基于对已获得的大量高质量数据的分析。不过，JCMT 还将做出进一步的观察。这些将包括开发改进的测绘技术、使用 JCMT 正在开发的 100 元件测辐射热计阵列 SCUBA 进行更长波长（长达 2 毫米）的观测以及由于振荡和可能的费用而引起的强度变化的观测。新计划还将包括对 1991 年 7 月 11 日莫纳克亚山日全食观测结果的初步分析。
