摘要

We study the photospheric evolution of a flare-productive ac-tive region (NOAA10930) on the Sun. Hinode's Solar Optical Telescope (SOT) provides us with the temporal development of vector magnetic fields in the pho-tosphere, which enables us to derive the magnetic helicity injected to the active region. The magnetic helicity is a quantity representing how much magnetic configuration is distorted, and we investigate a key feature of helicity evolution that relates to the occurrence of a flare. We show that the saturation in helicity evolution indicates the possible occurrence of a flare, which might be useful for the prediction of flares.
