Solar active regions are high-density, hot, and highly magnetic regions of the solar atmosphere associated with sunspots. This project takes several years of data from the Atmospheric Imaging Assembly onboard NASA's Solar Dynamics Observatory in order to study the properties of a large number of active regions, and changes in these properties over both short (~days) and long (~years) timescales. The main aim of the project is to find statistical relationships between certain properties (e.g. magnetic field variation and cooling/heating) and to interpret these relationships in terms of coronal heating models.

太阳活动区是太阳大气中与太阳黑子相关的高密度、热和高磁性区域。该项目从NASA太阳动力学天文台上的大气成像组件获得了几年的数据，以研究大量活动区的性质，以及这些性质在短(~天)和长(~年)时间尺度上的变化。该项目的主要目的是找出某些性质(例如磁场变化和冷却/加热)之间的统计关系，并用日冕加热模型解释这些关系。
