The PI will use a new narrow band coronal filter and new lightweight telescope techniques to observe coronal velocities during the total solar eclipse of 29 March 2006 in Kastellorizo, Greece. The PI's team will use two new high efficiency CCD cameras to record coronal loops at high cadence (5 Hz) to confirm and extend their previous observations of green line (5303 A) coronal oscillations. The observations will permit researchers to discriminate among competing models of coronal heating. The PI and his team also plan to use an existing high spectral resolution (0.16 A) Fabry-Perot etalon to observe coronal velocities by simultaneously constructing Dopplergrams of the same limb region during the eclipse.The proposed activity is designed to investigate coronal oscillations and their relationship to the causes of coronal heating, while providing teaching, training, and learning opportunities to undergraduate students in all aspects of the research. Students will perform preliminary work at Williams College in Williamstown, expeditionary work at the eclipse site, and then subsequent efforts through the summer, to include data reduction in student thesis projects. Fifty percent of the students involved will be female and one minority student is also included. Greek students and researchers will work with the U.S. team at the eclipse site in Greece, giving the U.S. students an international research experience.The activity will enhance the infrastructure for research and education through the new collaboration between Williams College and JHUAPL, by restoring a high quality filter that had previously been used only on balloon flights. The results of the expedition will be disseminated broadly. Each of the past successful Williams College eclipse expeditions has resulted in at least one published refereed paper and two meeting reports. In addition, the PI is the Chair of the International Astronomical Union's Working Group on Eclipses and serves on the Scientific Organizing Committee of an IAU Symposium on solar magnetic fields to be held just after the eclipse. Expedition results will appear through these and other suitable future venues. Finally, the PI is President of the IAU Commission on Education and Development, and the educational aspects of this expedition will be reported at an IAU General Assembly Special Session in August 2006, of which the PI is co-organizer. This proposal is co-funded by the NSF's Division of Atmospheric Sciences and Office of International Science and Engineering (OISE).

PI将使用新的窄带日冕滤光器和新的轻型望远镜技术来观测2006年3月29日在希腊Kastellorizo发生的日全食期间的日冕速度。PI的团队将使用两台新的高效率CCD相机记录高节奏（5赫兹）的日冕环，以证实和扩展他们之前对绿线（5303 A）日冕振荡的观察。这些观测结果将使研究人员能够区分不同的日冕加热模型。PI和他的团队还计划使用现有的高光谱分辨率（0.16 A）法布里-珀罗标准子，通过在日食期间同时构建同一边缘区域的多普勒图来观察日冕速度。该活动旨在研究日冕振荡及其与日冕加热原因的关系，同时为本科生提供各方面研究的教学、培训和学习机会。学生们将在威廉斯敦的威廉姆斯学院进行初步工作，在日食地点进行探险工作，然后在整个夏天进行后续工作，包括在学生论文项目中进行数据整理。50%的学生将是女性，其中还包括一名少数族裔学生。希腊学生和研究人员将与美国团队在希腊的日食地点合作，为美国学生提供国际研究经验。这项活动将通过威廉姆斯学院和联合地球物理研究所之间的新合作，通过恢复以前只在气球飞行中使用的高质量过滤器，加强研究和教育的基础设施。这次考察的结果将广泛传播。过去每一次成功的威廉姆斯学院日食考察都至少发表了一篇论文和两篇会议报告。此外，PI还是国际天文学联合会日食工作组的主席，并在日食之后举行的国际天文学联合会太阳磁场研讨会的科学组织委员会中任职。考察结果将通过这些和其他合适的未来场地出现。最后，PI是IAU教育和发展委员会的主席，这次考察的教育方面将在2006年8月的IAU大会特别会议上报告，PI是该会议的共同组织者。该提案由美国国家科学基金会大气科学部和国际科学与工程办公室（OISE）共同资助。
