题  目：On Solar Magnetic Helicity in Active Regions: some Observational Results

    报告人：Yang Liu （刘扬）博士 （斯坦福大学）

　　摘  要：Magnetic Helicity in Solar active regions is an interesting parameter that is used to describe magnetic complexity. Using HMI observation of vector magnetic field, we study helicity injection into the corona and examine hemispheric preference in active regions. In this talk, I will report progress we have make recently.
