This is a collaborative project between the SouthWest Research Institute, and two of NSF’s Federally Funded Research and Development Centers – the National Solar Observatory and the National Center for Atmospheric Research. In August of 2017, the Great American Eclipse traversed the continental United States from Oregon to South Carolina. The Citizen Continental-America Telescopic Eclipse (Citizen CATE) successfully deployed over 300 volunteer citizen scientists at 68 sites to continuously observe totality from coast to coast. That effort resulted in a novel and unique dataset containing 90 minutes of continuous coverage of the inner solar corona. On April 8, 2024, a total solar eclipse (TSE) will again traverse United States, this time from Texas to Maine. The project outlined here is to build on the successes of CATE 2017 and improve the observations with upgraded instrumentation to better observe the middle layer of the solar atmosphere (the middle corona). CATE 2024 project will deploy 40 teams of citizen scientists along the path of totality to collect over 60 minutes of high-resolution data which will be used to study several outstanding problems in the hard to observe middle corona. A previous planning work including site selection, identification of necessary equipment, and initial development of the citizen science network as already been carried out. This award is to carry out the planned activities, which includes equipment purchase and telescope building, coordination and training for the teams, data collection during the eclipse and preliminary compilation of the data. The broader impacts include engagement with Native American and other underrepresented community groups along the eclipse path, the donation of telescopes to the community groups for use in other astronomical observations, and the inclusion of an early career female scientist as the project manager. CATE 2024 will use high-cadence high dynamic range (HDR) polarimetric observations of the corona to characterize the physical processes that shape the heating, structure, and evolution of the solar corona at scales that cannot be studied outside of a TSE. The science objectives of CATE 2024 are to (1) determine the connectivity of structures that span the middle corona, where the coronal magnetic field transitions from primarily closed to primarily open; (2) measure the flow of the nascent solar wind, by characterizing small scale dynamics that occur during the eclipse; and (3) identify and characterize magnetic reconnection, which is believed to generate structure in the solar wind and to heat the low and middle corona, by identifying features and dynamics related to this process.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这是西南研究所和NSF联邦资助的研究与发展中心的两个合作项目 - 国家太阳能天文台和国家大气研究中心。 2017年8月，美国伟大的日食从俄勒冈州到南卡罗来纳州的美国大陆穿越。公民大陆 - 美国望远镜日食（Citizen Cate）成功地部署了300多名志愿公民科学家，在68个地点，不断地观察到从海岸到海岸的总数。这项努力导致了一个新颖而独特的数据集，其中包含90分钟的内部太阳能电晕的连续覆盖范围。 2024年4月8日，这次是从德克萨斯州到缅因州的太阳日食（TSE）将再次穿越美国。这里概述的项目是基于Cate 2017的成功，并通过升级的仪器改善观察结果，以更好地观察太阳大气的中层（Middle Corona）。 CATE 2024项目将沿着整体发展40个公民科学团队，以收集60分钟的高分辨率数据，这些数据将用于研究难以观察到的Middle Corona中的几个杰出问题。先前的计划工作，包括现场选择，必要设备的识别以及已经进行的公民科学网络的初步开发。该奖项是为了进行计划的活动，其中包括购买和望远镜大楼，团队的协调和培训，日食期间的数据收集以及数据的初步汇编。更广泛的影响包括与美洲原住民和其他代表性不足的社区群体的互动，向社区群体捐赠望远镜，以用于其他天文学观察，以及将早期职业女性科学家作为项目经理。 CATE 2024将使用电晕的高振动高动态范围（HDR）极化观测值来表征在无法在TSE之外研究的尺度上塑造太阳能电晕的加热，结构和演变的物理过程。 CATE 2024的科学目标是（1）确定横跨Middle Corona的结构的连通性，其中冠状磁场从初级封闭到原发性开放式转变； （2）通过表征日食期间发生的小规模动力学来测量新生太阳风的流动； （3）识别和表征磁重新连接，据信这可以通过识别与此过程相关的功能和动态来产生太阳风中的结构，并加热低调和中间的电晕。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来通过评估来获得支持的审查标准。
