Hinode (Solar-B) successfully captured a massive flare occurred in active region NOAA 10930 on 13 December 2006. It was one of the largest flares occurred in the period of solar activity minimum. Data obtained with three telescopes on Hinode are in good quality. X-ray Telescope (XRT) saw high temperature coronal loop and detected wave propagation associated with the flare. Solar Optical Telescope (SOT) found the collision of two spots well in advance of the flare, which implies the twisting of magnetic fields in the corona. Extereme-ultraviolet Imaging Spectrometer (EIS) detected supersonic eruption during the flare. This is the first time to get high resolution comprehensive data set ranging from magnetic fields, which are the energy source of the flare, and dynamics of high temperature plasma produced by the flare. Hinode team is now intensively studying the precious data.
