초록
Canceling magnetic features (CMFs) are likely to be a result of magnetic reconnection in the lower atmosphere of the Sun. CMFs are related with chromospheric phenomena such as brightening or jets. In order to observe the fine-scale and highly dynamical structures in the chromospheres, Fast Imaging Solar Spectrograph (FISS) was developed and installed at 1.6 m New Solar Telescope at Big Bear Solar Observatory. Using this FISS data we have studied chromospheric brightenings associated with CMFs. As a result, the chromospheric brightenings related with CMFs have stronger shock waves than one of other regions such as internetwork regions or unipolar magnetic elements
