We show that the surge activities correlate well in time with the cancellation of magnetic fluxes around an emerging flux region. In particular, the highest surge in Hα and the brightest emission in TRACE 1600 A images was related to the most pronounced cancellation of magnetic flux in one small area. These facts are consistent with the magnetic reconnection model. We found a spatial displacement between the area of magnetic cancellation and the bright area in UV images, which was about 8000 km in plane of sky. We could not find any bright structures in soft x-ray (SXR) and EUV images during this surge active phase. These may be clues for detailed modeling of surge activities.
