今天我想介绍一位客人博主，大卫驻军，他是Mathworks的Matlab产品经理。这是未来几个月的一系列博客中的第一个，描述了MathWorks参与令人兴奋的项目与2017年日食有关的令人兴奋的项目。

这是该系列的第1部分。

内容

这2017年Solar Eclipse

正如你少年的所知，2017年8月21日将在2017年8月21日出现一系列总日食，其中总体的路径将通过美国大陆。这是一个罕见的事件。来自美国的最后总eclipse在1979年2月出发。2017年Eclipse的总计路径在下面的地图上显示。

对太阳能的天文学家,日食是最好的time to observe the sun’s corona (its outer atmosphere). The glow of the corona is a million times less bright than the sun’s photosphere so the only time to observe and gather data on the corona is when the sun’s disk is blocked out during an eclipse. The 2017 eclipse will provide solar astronomers an unprecedented opportunity to gather data. That data will be used for both static and dynamic studies of the corona.

这公民cate实验

这公民cate实验is a citizen science project run by the National Solar Observatory (NSO). Dr. Matthew Penn is the project's Principal Investigator. The project's objective is to capture images of the sun's corona at sites along the eclipse path using a network of telescopes operated by volunteers. Those volunteers include high school and university groups, astronomy clubs, and individuals. Here is the project’s vision:

这CATE Experiment should unify people from coast to coast, make them aware that they are part of something bigger than themselves, re-ignite a new wave of citizen science, and inspire students by showing them a path to becoming a scientist.

志愿者将使用一套标准的设备，包括望远镜，相机和项目的笔记本电脑。软件将用于获取相机图像并执行数据的一些初始预处理。拍摄数据后，它将上传到NSO服务器并提供给公众。可以找到项目科学目标的完整描述here。

Volunteers will be trained by state coordinators in equipment use and data collection. After the eclipse, volunteers will keep the equipment or donate it to a local middle school or high school. There is interest from other researchers in using this network of volunteers to do future large scale astronomical studies.

MathWorks Involvement in the Project

我第一次听说我参加过2015年的公民cate实验东北天文论坛（奈特）– a conference and tradeshow for amateur astronomers. Dr. Penn was one of the speakers at the conference and described his idea to create a network of citizen scientists spread out across the continental U.S. to image the eclipse. As I watched his presentation, two thoughts occurred to me. First, as an amateur astronomer, I wanted to be involved in the project as a volunteer. Second, the eclipse will be a big science event in 2017 witnessed by millions of people in the U.S. and maybe there is an opportunity for MathWorks to help.

题目介绍后，我将我的名字提交给一个项目志愿者。我被接受，并将收集田纳西州哈特斯维尔的日食上的数据。另外两位数学工作人员志愿者，并将观察南卡罗来纳州地点的蚀。MathWorks还同意成为公民Cate赞助商。我们正在提供一些财务支持以及为志愿者提供软件。金宝app在Citizen Cate网站上可以找到项目赞助商的全部列表。

在Eclipse期间，志愿者将使用MATLAB，图像采集工具箱和图像处理工具箱从Eclipse记录和处理图像。图像将以几种曝光记录并组合成一组高动态范围图像的电晕。有关随后的帖子中的更多细节。

What are Your Plans for the Eclipse?

你打算去看Eclipse吗？您所在地区有当地的日食事件吗？我们很乐意听到你的计划here。

接下来：培训志愿者

目前为止就这样了。在我的下一篇文章中，我将描述项目的设备和软件以及培训公民Cate志愿者的过程。
